Well, 2 points, we have not been collecting enough for needed work.......and....those dollars are often diverted because there are NOT enough revenues for the rest of the budgets.How much is collected from taxpayers from gas taxes, tolls, driver and car licensing, traffic fines/penalties, etc.? Then tell us how much of that is actually spent on maintaining roads and bridges and not just flushed down the general revenues toilet.
But all of this is a diversion from the point, which is that you have once again contradicted your argument, first arguing for taxation for public works, then an about face and calling for cuts.
Tax expenditure by a nation is fundamentally different from individual expenditure. The former is basically redistribution of resources- what is taken from one area is given to another. The question of wise expenditure is a managerial issue, just as it is in the private sector. We've seen some very bad decisions in both, but that does not negate the need for public participation in the economy.
Taxation was essential in escape from the great depression of the '30s, and then in helping the post war boom after WW2. Social programs born out of the desperation of the depression helped to build the middle class society we see today (although it is fading, as the lessons of the past are forgotten by an apathetic populace today).
Without the planning functions allowed by a tax system, we would end up with a few Walton families and similar, a few (God help us) Donald Trumps, and a lot of peons running about hoping to earn a few pennies, and take them back to their rusty trailers. Or worse than that, we would have Somali style warlords.
