No, it most certainly is a property of capitalism. Or are you going to try and tell me that trying to gain an advantage by bribing politicians is somehow not a property of capitalism?
If the Federal government were limited per the Founders' intent (most everything handled at the State level), then the Federal politicians wouldn't have the power to grant you your every whim if you handed them a pile of money.
By allowing the Federal government nearly unlimited power to do good, you also allow it nearly unlimited power to do evil.
And guess which side has more money to bribe politicians?
Why does it matter if the bribe-able politicians work on the federal level or the state level? If those powers were given to the states, then the states' politicians would be the ones being bribed. The result is the same.
The libertarian argument that the federal government should be considerably weaker and that state governments should be considerably stronger in its stead makes no sense to me whatsoever. And I live in one of the very wealthy states that would probably benefit from such a change.
