And you determine when that benefit ends? You tolerate them? How nice.
I guess Adam Smith is a dirty word to you anti-traders.
"IT IS NOT FROM THE BENEVOLENCE OF THE BUTCHER, THE BREWER, OR THE BAKER THAT WE EXPECT OUR DINNER, BUT FROM THEIR REGARD TO THEIR OWN SELF-INTEREST"
Works for corporations too. The benefit from corporations isn't because they're trying to be nice or do what you think they should do but because in their greedy little profit maximizing way they provide employment and goods which by their very nature benefit society.
Not really. Smith's "the butcher, the brewer or the baker" are the REAL people.
Corporation is a legal CONSTRUCT and a curtain behind which the actual players can hide to avoid personal responsibility. This can be beneficial for the society as the incorporated people might experiment without much fear.
If the general benefits from this immunity are larger than the losses from unprosecuted errors/fraud then the allowing, maintaining, protecting or even subsidizing by the taxpayers makes sense. If corporations become the tool for looting, treason and impoverishment then it is time to end the shell game.
