Government Sponsored Sectors

"Ain't nobody clean. Be nice to get clean, though"
--Tripp (Glory)

Which industrial sectors do substantial trade with the federal government, both in terms of economic resources and influence (contracts, subsidies, tax breaks, monopolistic grants, favorable regulatory treatment, etc), thereby making them government sponsored sectors? It would probably be quicker to list those sectors that have not received such treatment. 

But let's list some of the largest:

military/defense

healthcare

education

We've noted those before. Perhaps think of them as the Big Three. But there are others:

finance

utilities

transports

media, particularly social media

housing/real estate

law

accounting

agriculture (e.g., corn/ethanol subsidies)

energy, greens in particular

There are others. Recently in the news: automotive working w feds on electric cars, computer chip industry getting government support for domestic factory capacity adds.

When you think about it, few sectors are truly free and clear of government influence.
