Your argument is moot. We tax ourselves enough to fix every bridge/road/highway/tunnel in the entire world twice-a-year, but only 1% goes to the Department of Transportation. There are plenty of valid arguments out there for taxing more but please don't give me the 'we need better infrastructure' bit.
Also you can tax the rich all you want but history shows at the end of the day the government will pull in 18% of the GDP as revenue. No matter what the tax code has been they always end up with the same amount of income. They have to spend as much as they take in. Period. The worst part is that for the past 20 years roughly 10% of the GDP is actually them overspending; so think about that after ten years of that - they have pumped in an entire year of GDP of 'fake' demand. Money getting moved around creating jobs that are unsustainable - unless we borrow even more. Think about that - the housing market - electronics - services; anything and everything has been inflated by their overspending.
So here we are - best case scenario we smarten up and cut back by about 10% on government spending every year for 10+ years (under what they take in that is). Things will continue to get worse but we'll make it. The other scenario is we continue to play 'kick the can' or default. Some could argue the government should default as it was their fault for getting in this mess - but think about who gets affected; social security, medicare, infrastructure, pensions, etc... Do the banks or the rich lose anything? Those that benefited most by the pumping of the money in the system. Kicking the can is just as bad - as the fall becomes much much worse the longer we put it off. Oh, and it is all just math - nothing to do with political views - the math will balance out there is no question.
