"Bribery exists in every economic system" is not an argument for being okay with bribery in this system.
When bribery happens in a country with a command economy, do you still say "there's that invisible hand of capitalism again"?
Bribery is not connected to a free market per se, but bribery in a free market is still a problem to be solved in the context of that free market.
Yes of course. I don't know why you keep suggesting I am against that. My issue is with the nonsensical attempts to tie bribery to capitalism, as if one is the result of the other.
