Kev, watch out there! Too many brains (as your post displays) might get you listed!!! Watch out!!
In the early '80s, Big Oil received a Forever Tax Break worth tens of billions so they could start building new refineries in the USA. Know how many have been built since then? ZERO. The Americans should demand every penny of that back from those companies that promised to build and then refused to, padding their profits from an "entitlement" handed over by that president and every Congress since then.
Or what about tobacco subsidies? Could the US afford to put two states' farmers into a re-growth path and forego their large foreign profits? Cancer Research gets kajillions and it's paid off - uh - how?!! Cancer Research is so incredibly profitable that even States are setting up their own money-centers called 'research labs'.
And for all the doom & gloom that the Health Care lies about, why is hospital building spending higher and higher every year? NO ONE would spend money on new hospitals if they weren't huge profit centers, too. Does anyone live in a city without a massive new hospital being built?
Kev, I'm listing these are brief examples that are either rebuttals to your thesis or actually quite supportive of those facts. But "lies and deflections" are seemingly omnipresent, so those ulterior motives - always with lotsa dollar signs - remain cloaked, according to those wishful thinking liars.
(I admit that I have personal benefits from Farm Subsidies, by the way, but their original goal was to stabilize a farm's value over time, regardless of market and climate forces. Of course, we've seen those noble goals perverted by greed - "Let's make farms fail so Big Ag can buy them for a song and redirect taxpayer incomes into monopoly pockets.")
