> Have you ever actually worked in a start up?

Yes, many in fact. We negotiated the terms up front and if I didn't like them then I went with another offering company. I never had deals change from under me, maybe you're some Eduardo Saverin but I'm not. That you got screwed for not doing your due diligence doesn't mean everyone does. I'm not sure what is immoral, unethical, or unfair about that when again no one is forcing you to work at any particular company or even startups, or even in the tech industry. There are lots of jobs you can do.
