I would be happy. I'm not an executive so I don't get executive pay. The executive salaries at Wikimedia seem low compared to what you can earn at a similarly sized business.
It's not really a business.
Non-profits shut down all the time. If you're concerned about a lasting impact you'll pay for a talented executive team.
The biggest set of responsibilities charites I didn't list is sales (aka donations). But Wikipedia doesn't do more good work (as donors think of it) the more money they get. It doesn't scale up much that way.
