Interesting note from an editorial in today's Wall Street Journal:

[T]akeovers are an underappreciated tool of corporate finance. They inject efficiency and discipline into the markets and can often be a check on rogue or inept management. Even hostile takeover attempts that are unsuccessful can light a fire under management and lead to improved shareholder returns.
Ah, they're probably just talking about the Chrysler thing.
