Why is stock dilution legal?
Alot of these answers have focused on the dilution aspect, but from a purely legal aspect, there are usually corporate bylaws that spell out what kind of vote and percentage of votes is needed to take this type of action.  If all other holders of stock voted to do this, so 90% for, and you didn't, so 10% against, it's still legal if that vote meets the threshold for taking the action. As an example of this, I known of a startup where employees got $0/share for their vested shares when the company was sold because the voting stock holders agreed to it.  Effectively the purchase amount was just enough to cover debts and preferred stock.
