A recurring theme of this year’s presidential campaign is the need to encourage the formation of new businesses. Republicans in general, and Mitt Romney in particular, have stressed that the best way to stimulate such startups is via low tax rates on high-income earners.
Romney wants to cut top rates by 20 percent, maintain the favorable treatment given to capital gains and dividends, and completely eliminate the estate tax, which currently only kicks in on estates in excess of $5 million for an individual or $10 million for a (heterosexual) married couple.
In other words, this is a strategy that emphasizes maximizing the after-tax returns if and when you hit it big. Yet if you think about the way most new businesses are started, it should be clear that these tax incentives have very little to do with the decisions facing most new entrepreneurs.
