Dan,
You're a brilliant guy!
The current tax scam is a tier game. Over Xn amount salary and you pay more percent tax. If the tax tiers stay the same, all that's done is everyone shifts tax tiers, but doesn't gain. The result is what economists term, stagflation.
1) all wages go up
If everyone has more money and supply remains constant. One of two thing happen: people rapidly buy the good and supply is gone or price increases to the point of steady state, previous to wage increases. Which is magically the same as the percent wage raise. You think companies will increase supply rather than more profits?
2) That salary has increased by Xn percent inflation, but the tax scam put you in a higher bracket(Yn = percent of salary to buy goods), so your have Yn current becomes less than Yn previous.
3) the richest already can't pay more percent tax. So their after inflation increase minus taxes that proportionally stayed the same, means only the highest tax bracket gained under your new living wage for all plan.
This is why socialism sucks. Under government socialism, the rich get their money stolen to redistribute to the poorer. Under corporate socialism, the US' current economic system, the rich with the government as their strong arm, steal from everyone else.
The only fair system is egalitarian laissez-faire capitalism, with only enough government watchdog action to prevent individuals from forming corporations and/or syndicates. Like no dumping laws. Then it becomes the laws of economics, not biggoted social programs, who becomes better off.
