...do so many companies try to get government business?
Privately run prisons
Military contracts
Highway and bridge contracts
Private schools with government vouchers
Sports stadiums with tax money
And to boot they want government to protect their businesses with
Courts to adjudicate disputes among companies
Courts to protect copyrights with large judgments against individuals (what's this about tort reform?)
Enforcement of patents
Trade negotiations
Employees educated and trained at government expense
I'm sure you can think of many more things that governments want from government without paying any taxes to support their wish lists.
Like a little kid, they want the tooth fairy to leave a quarter under their pillow every morning. That's a quarter million or even a quarter billion.
