I think people keeping their own money is more important than maximizing government revenues.
Cutting taxes doesn't mean people will "keep more of their own money"...the household debt figures completely undermine that wild claim. Sure, you're saving money in income taxes, but sales taxes, excise taxes, user fees, tuition, health care costs, public transportation costs, etc. all rise to make up for the gap created by income tax cuts. Those cost increases affect the middle and lower class more than the wealthy.
But that's always been the Conservative goal; you lack the courage and support to repeal legislation you are ideologically opposed to, so instead you try to Trojan Horse it by reducing government revenues deliberately in order to manufacture deficits that you then use as an excuse to cut the spending you are ideologically opposed to, but lack the courage and support to repeal through legislation.
We know the game by now...Norquist revealed it in the 80's. Amazing that in 30+ years, Conservatives have not changed their dogma one iota. That proves they are regressive and out of touch.
