"From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked." (Luke 12:48, NIV); taxes must be progressive
Trump's tax ideas are lunacy
It is undoubtedly the silly season in American politics. I asked GPT-4o what it thought of Trump’s idea to replace the income tax with tariffs. While I can see the benefit of a national sales tax, which a tax on tariffs would essentially be, it would be highly regressive as a replacement for the income tax. Taxes on consumption are considered good because they encourage saving and investment. Given the level of inequality in our society already, I think it would be better to work on deregulation and keeping the tax rate on capital gains low. Our social fabric is already busting at the seams.
As I have already written, protecting American industries from international competition too much guarantees that they will all become puny weaklings. Targeted protection, such as in technology, makes some sense.
Via GPT-4o:
what would the effect be of replacing the US income tax with tariffs on imports designed to raise the same amount? is this a feasible idea?
Replacing the U.S. income tax with tariffs on imports to raise the same amount would represent a massive restructuring of the nation’s tax system, with profound implications for the economy, international relations, and income inequality. Here's a detailed exploration of the potential effects and feasibility of such a proposal:
Effects of Replacing Income Tax with Tariffs
Increased Consumer Prices
Tariffs Directly Affect Prices: Import tariffs are a tax on goods entering the country. Imposing higher tariffs to raise the revenue equivalent to the entire federal income tax system would significantly increase the prices of imported goods, and likely domestic goods too. Since many everyday products (such as electronics, clothing, and certain foods) are heavily reliant on imports, consumers would face considerably higher costs.
Inflationary Pressure: This shift could contribute to higher inflation, as businesses pass on increased costs to consumers. Inflation would especially hurt lower-income households that spend a larger portion of their income on essentials, many of which are imported.
Potential Trade Retaliation
Retaliatory Tariffs: U.S. trading partners are likely to retaliate by imposing their own tariffs on American exports. This could damage the competitiveness of American industries abroad, particularly those that are major exporters, like agriculture and technology. A trade war could ensue, leading to lower demand for American products internationally and causing economic contraction in sectors reliant on exports.
World Trade Organization (WTO) Rules: Such a drastic move would likely be against WTO regulations. The WTO's purpose is to ensure fair trade, and replacing income taxes with tariffs could lead to disputes and sanctions, isolating the U.S. economically.
Impact on Domestic Production and Employment
Boosting Domestic Production: On one hand, high tariffs might encourage consumers to purchase domestically produced goods, potentially boosting domestic industries. This could lead to increased employment in sectors that produce substitutes for previously imported goods.
Disrupting Supply Chains: However, many industries depend on global supply chains and imported intermediate goods. Imposing steep tariffs on these imports could significantly increase production costs for American manufacturers, leading to potential job losses, reduced competitiveness, and even the shutdown of some industries.
Industries at Risk: Industries like automotive manufacturing and technology, which rely on imported components, would face increased costs that could diminish their global competitiveness.
Revenue Uncertainty
Volatility of Tariff Revenues: Unlike income taxes, which provide a relatively predictable and stable revenue stream, tariff revenues depend on the volume of trade. Trade volumes can fluctuate due to changes in the economy, global market conditions, or consumer preferences. A recession or changes in international trade patterns could lead to significant declines in revenue, affecting government funding for essential services.
Difficulty in Achieving Revenue Goals: The federal income tax brings in more than $2 trillion annually. Raising a similar amount purely through tariffs would require extremely high rates—likely 100% or more on many categories of imports. This would be unfeasible in practice, as import volumes would likely drop significantly, leaving a substantial shortfall in government funding.
Income Inequality
Regressive Effect: Tariffs are generally considered a regressive form of taxation, as they disproportionately impact lower-income households. Everyone pays the same higher price for goods regardless of income, meaning that a larger share of a low-income individual’s budget goes toward basic necessities. In contrast, the current income tax system is progressive, with higher earners paying a larger percentage of their income in taxes. Moving to a tariff-only system would likely increase income inequality.
Feasibility of Replacing Income Taxes with Tariffs
Political Barriers: Such a radical shift would require significant political will and legislative changes. Given the dependence of various industries on global trade and the potential impact on consumers, this idea would face substantial resistance from both industry groups and the general public.
International Relations: The U.S. has numerous trade agreements with other countries that are designed to reduce barriers to trade. Replacing income tax with tariffs could violate these agreements and damage relationships with key allies and trading partners, leading to a decrease in international cooperation.
Economic Theory: Mainstream economic theory generally supports free trade as a means of maximizing economic efficiency. High tariffs that distort trade flows are generally seen as reducing overall economic welfare. Many economists would argue that income taxes—despite their complexity—are a more efficient way to raise government revenue without severely impacting consumer choice or international competitiveness.
Conclusion
Replacing U.S. income taxes with tariffs on imports designed to raise the same amount is not a feasible idea from both practical and economic perspectives. The potential for high inflation, retaliatory trade actions, increased income inequality, and revenue volatility make this an impractical solution for maintaining government revenue and economic stability. While it might boost certain domestic industries, the overall economic disruption, impact on global trade, and harm to consumers would far outweigh any potential benefits.
