They aren't going up by 40 percentage points for anyone. And probably not, as a result of the expiration, even 40% (which is a far smaller increase, if you pay 30% taxes, a 40% increase would only be an increase to 42%, not to 70%). But people will pay the 40%, and that 40% impacts their decision making. You can break taxes down in to any number of tiny parts. You can say "no one is going to change their behavior for an extra one percent of tax", but that's not actually true. If it was literally true than you could keep increasing taxes by a one percent until the tax was 100% with no impact on people's decisions. Each small bit of increase puts some new people at the margin, and they are the one's who change their behavior. Its unlikely to be a smooth curve, with every 1% increasing being equal to all others. But neither is it the case where there is no impact until the taxes are at some specific very high level. he proposal is to take it from 36% to 39% for incomes over $250k A new or increased phase out of deductions at around the same point pushed the marginal tax rate at that point up to the low 40s. Which for most affected by the tax is going to be far less than even 3% since the first $200k or $250k is still taxed at a lower rate. Which isn't a major point in terms of incentives since the marginal dollar will get taxed at 39 percent or more. And we all remember how crappy the economy was from 1994 to 2000... Because of course tax rates are the only thing that impacts the economy, and if the economy is good after some changes in tax rates, that change automatically had to be good for the economy... So tax cuts have to be good, since the economy did well after Reagan's tax cuts, tax increases have to be good, since the economy did well after Clinton's tax increase. I guess changing the tax rates is good for the economy, why not do it every day, then the economy will zoom to the moon (if we follow your logic).
