Should the wealthy pay a higher tax rate than they currently do?

The question of whether the wealthy should pay higher tax rates is a longstanding debate in economics, politics, and ethics. It involves trade-offs between equity, efficiency, revenue needs, and incentives. I'll outline key facts, arguments on both sides, and evidence, drawing on data and research rather than pure opinion. Note that "wealthy" typically refers to high-income earners (e.g., top 1%) or high-net-worth individuals, and "tax rate" can mean statutory marginal rates, effective rates (after deductions/credits), income taxes, capital gains, wealth taxes, etc.
