Why Everyone Should Be in Favor of Reducing Taxes on the "Rich"

George Reisman explains why Obama's tax the rich plan will lower the standard of living across the board, including for wage earners:

The progressive personal income tax, the corporate income tax, the inheritance tax, and the capital-gains tax are all paid with funds that otherwise would have been saved and invested. All of them reduce the demand for labor by business firms in comparison with what it would otherwise have been, and thus either the wage rates or the volume of employment that business firms can offer. For they deprive business firms of the funds with which to pay wages.

By the same token, they deprive business firms of the funds with which to buy capital goods. This, together with the greater spending for consumers' goods emanating from the government, as it spends the tax proceeds, causes the production of capital goods to drop relative to the production of consumers' goods. This implies a reduction in the degree of capital intensiveness in the economic system and thus its ability to implement technological advances. The individual and corporate income taxes, and the capital-gains tax, of course, also powerfully reduce the incentive to introduce new products and improve methods of production. In all these ways, these taxes undermine capital accumulation and the rise in the productivity of labor and real wages, and thus the standard of living of everyone, not just of those on whom the taxes are levied.
