There are voting and non-voting shares. Non-voting shares have no control whatsoever.
Not if the government takes over the business. I completely understand the problem with risk. If the business goes bankrupt then I lose the value of the share. If the government wants to take over the business, then they have to compensate me for the value of my property. They just can't take it.
So what you are saying is anyone who owns shares in any bank that has TARP funds should immediately sell to avoid the risk of nationalisation? Oh, that's really helpful. I'm sure that's what the government wants, to have struggling banks go completely broke.
or at least have the choice of selling before the government takes over.
