OK, I'm only going to do this once.
Tax cuts make everyones stuff more valuable. If you own a business and receive a real tax cut, an income tax cut and a capital gains cut, the stuff you own becomes more valuable to you. So then most business people will now go out and buy and sell more of the stuff because they get mo' money from it net after tax. There's more activity, people take money out of their savings and/or will go to the bank or investors for more capital because they can put that capital to work buying and selling the stuff that just became more valuable. Then they have to hire more people to find more stuff and keep track of the stuff they already own.
Tax cuts BOOST the economy because everybody's stuff is more valuable. As the economy grows the gubbamint collects more revenue from the additional activity.
Vote for me in 2012 and I'll make your stuff more valuable
the only relationship between asset value and tax cuts in an underfinanced government model like ours in the US is inflation.
do you really think businesses endeavor to trade less because of taxes, more when there's a tax cut? i could understand businesses investing more profits in capital as a tax shelter.
the post-reagan tax-cut economy boost is something mostly appreciated by market investors and the like. it seems to increase the share of that activity in the economy. stocks, while great fun and good money for some, are not really a dominant factor in the economy.
not like the government does. the public sector is a big one which puts more wealth into the economy than the stock market, by far. it better facilitates commerce, hires more, spends more and is more stable. uncle sam doesnt run a tight ship, but you've almost entirely written off the value of the public sector in the economy, then proposed a lesser component in its place.
good ol' mainstreet capitalism and investments in real biz, not large, public firms, account for the majority of jobs and the majority of wealth in the US. there's little virtue in wide sweeping cuts. history dictates as much. targeted tax cuts which bolster specific deductions, however, seem to help real-world people save or build businesses.
