Yes Trillian. My DH works for one of these big evils (you know, pollution, greedy etc), and we have bought shares in them.

Although i don't have shares in banks, i think this is much the same. You never hear of banks having to sell their buidlings in mortgagee sales!

Oh, and the return we get on the 'evil' shares is not huge (because they keep expanding and buying more infrastructure) but the share price has steadily increased.
