Whatever the optimal tax code, and whatever Americans should pay, the US is not burdened by a prohibitive tax code that stifles growth. I read somewhere that federal taxes are 14% of GDP, the lowest since 1940. More than half the people in this country don't pay income taxes. America has one of the lowest tax takes in the developed world.
Bingo. Whatever taxes are they have to match expenditures, period. lowering taxes today in the hopes of stimulating greater revenue in the future is a sleazy way of spending tomorrow's prosperity today.
And while that might be a cool idea if used rarely, our whole economy is based on that same trick.
It is great that our economy has maintained 2% growth for 150 years. But 2% growth isn't enough. We need 2.5% -3.5% growth each and every year to keep the monetarism machine fed.
And if we cheat the future of it's prosperity for short term advantage today then we will need even more growth in the future just to keep the money lending machinery fed.
It's all a bunch of tricks, just like the accounting tricks that CA has used to balance the budget without cutting spending. Like moving the fiscal year backwards one month to save one months spending, or cheating the counties out of sales tax revenues with promises to repay it in the future.
IOW there is no such thing as an optimal tax. Unless it is a mandatory pay as you go tax structure.
Whatever you spend, you have to pay for, with taxes and revenues. TODAY! No deferment of today's liabilities into the future.
All of the prosperity enjoyed in the US in the last 20 years came as a result of gimmicks to create artificial wealth today that would have to be dealt with later.
Dot Com bubble, housing bubble (those two cost us $11 trillion or more than an entire year's GDP) derivatives bubbles.
Our whole economy has been based on ponzi like schemes that eventually deliver predictable ponzi like results.
We gotta stop this shit asap.
Beginning with paying taxes to cover what we really spend.
Period!
