Because we voted for them.
The fraud of representative democracy. What about those who didn't vote them (the tyranny of the majority)? We, the common citizens, have really any power if our vote is secret?
The rights and obligations of a contractual act are generated by explicit consent of both members. This does not happen when we our vote is completely secret, without our names and surnames. Politicians are free to impose their monopolical powers, even if we don't choose them.
“Representative democracy is the illusion of universal participation in the use of institutional coercion."
We didn’t vote for the board of directors of private companies.
Because we shouldn't. Except for the lobbyists, they are using their private property and their factors of production achieved by social-cooperation.
There’s plenty of waste and corruption in private enterprise. It’s not voluntary if they lie cheat and steal just like bad politicians.
The only difference is that, in a free-market setting, they wouldn't have any monopolical privileges to mantain their economical power and reputation in the market, as their permanence is dependent of supply and demand.
Forced by who? By an oligarchy of politicians that are being influenced by those companies, and viceversa?
