That's a shitload of reading, Brass. Look at it this way: if taxes are raised to 100%, who would work? If taxes are dropped to 0%, who wouldn't work? Obviously, taxes negatively affect growth rates. People don't work for free. That's why we don't work for free. Laffer curve etc etc. The "optimum level" is optimum for who, exactly? Not for the worker who actually earns the income. No! For the Government, who wants to maximize their revenue, power, control, and influence over the affairs of the State. That in itself, is antithetical to free-market, libertarian-minded countries, like America, where the primacy of the individual to pursue their own (economic) happiness unmolested by Government, is a God Given Right. Even if revenue could be maximized at 60, 70, or 80% tax rates (bullshit), to what productive end would that serve? The Government is horribly inefficient at administering anything it touches, bureaucrats are notoriously underworked and grossly overpaid, lines are long, paper work takes months. Why pay the Feds, who pay the State, who pay the municipality, who pay the Contractors, when you yourself, can just pay for the services you want, and cut out 3 levels of Government middlemen who do very little but take a generous cut and waste your precious time? The Feds already have gobs of cash and look where it goes: Killing millions of brown people in Iraq, Afghanistan, 25,000 dollar shovels to KBR, drones in America, TSA legions molesting us at airports, cops writing tickets on every corner, cameras in the streets, bloated pensions for bureaucrats that plot to steal our rights. Half the budget is spent on destructive shit that kills people and lines the pockets of defense contractors who make weapons for useless wars. And this Government is what you want to empower with even MORE MONEY? See, Obama was supposed to change all this shit. Mr Touchy-Feely-Big-Heart-Liberal-Nice-Guy. But he didn't. He's a sell-out, like Bush was. The problem with Government taking shitloads of our money: they are corrupt pieces of shit who will waste it on war, fucking our rights, and graft to their corporate donors. Thats why *even if* a 70% tax rate maximized revenue, we should never do it. The criminals in DC cannot be trusted. Ever. It's a pipedream. Maybe if some angel ran Government, but they never do. It's this notion Liberals have in their head that Government is good, and Huge Government is even better. That's wrong. Huge Government is a threat, and small Government is best. This isn't a perfect world, man. We're dealing with the spiritual nature of man, which is corrupt. Empowering gigantic Governments (who are run by people), to Lord over us, even with the best intentions, leads to tyranny and despotism. That's the reality of it. We're getting a healthy dose of it already. And I don't like it. Mr Constitution passes the NDAA, CISPA, and flirting with the Enemy Expatriation Act. This is not the kinda of Government I trust with 70% of my pay check man. DO YOU?
