When government is trying to raise tax revenue, it sometimes attempts to target higher-income people because they are in a better position to bear the burden of a tax.

S. federal income tax system: It's designed so that higher incomes are taxed at higher tax rates. Thinking about the elasticity of labor supply, why might it be more difficult to collect tax revenue from a wealthy individual than from a poor person, all else equal
