Sure, help them out, but set conditions. The following should be in force until they've paid back the support in full:
No stock buy-backs
No payment of dividends
No bonus payments
Aid shall be earmarked to protect the employees; no lay-offs
No raiding of pension funds
Renumeration for executives set to a maximum of 10x the lowest paid employee
Government to gain ownership commensurate with the aid given, to be sold off when the markets eventually rebound
