I thought of an interesting argument while writing a novel just now:

  1. Suppose senators are paid a fair amount of money (this isn’t actually possible but we’ll assume the audience is statists).
  2. At some point, some legislator is bound to propose a bill that raises the pay that senators receive.
  3. Since the only people voting on it are senators, this bill is bound to be accepted since everyone is incentivized to vote for it.
  4. Therefore it is almost certain that senators are paid too much, because if ever they aren’t, they will promptly ‘fix’ that. The only thing that could ever stop them from raising it further is the threat of revolution.

QED. Let’s go ahead and add “forces certain people to be paid greater than the equilibrium price” to the evils of government.
