Tax cuts for the rich won't "create jobs." I believe there should be tax cuts for the entire population as a whole, not just the rich - and $250,000 a year is not rich.
Unemployment levels will decrease once the time preferences are back in shape. Continuing to keep interest rates at nearly 0% skews the time preferences and entrepreneurs are unable properly estimate present and future costs and prices (Interest rates a premium - since people always prefer money today than money tomorrow, present goods always command a premium in the market over the future). This artificial hampering with interest rates (intervention) sends out wrong signals for businessmen. They begin to invest in capital and producers' goods; previously unprofitable investments now look profitable, even time-consuming projects. Entrepreneurs begin to act as if savings genuinely increased, though all that has happened was the artificial lowering of time preference. Businesses ramp up borrowing from the newly created bank money and invest in capital goods, which then leads to higher wages because of artificially increased business demand (which seems to be no problem at the time because of the artificially low interest rates). When these higher labor rates are paid out to the workers, they begin to spend it on consumer goods because time preferences of the general public have not actually changed to the downside - they don't want to save more. This is an attempt by acting individuals (persons in an economy) to readjust the consumer/savings proportions (time preferences).
So, the money goes to the consumer goods industries and the capital and producers' goods are left hanging. This is when depressions (or if you're a Keynesian, recession, downturn - whatever name you want to put on it) set in after the artificial boom. A depression is when an economy tries to readjust itself and rid itself of all the malinvestments, which in this case is the overinvestment in capital goods. This is when the newly created money, not genuine savings, filters through the economy and businesses realize that the savings were not real and they have made a gross malinvestment. The artificial, inflationary boom caused by government intervention in interest rates causes price distortion and production system perversion. Prices of labor and capital goods have been pushed higher to unsustainable and unprofitable levels. The depression is a necessary phase in economic cycles to flush out malinvestments and return back to natural consumer/savings rates, time preferences.
Tax cuts mean nothing when it comes to unemployment and continuing to artificially contain interest rates at 0% levels will only make the next adjustment (depression) worse.
