Selling Future Earnings

This is an interesting idea for artists as well:

In a recent discussion among a select group of social investors and entrepreneurs a funny question was presented. If an investor offered you a large infusion of unrestricted capital, say $300,000, with the only condition being that you would give them 3% of your income for the rest of your life, would you take the deal? To the host’s delight, the conversation struck a controversial chord leading to 100 unique email responses about the idea.

What do you think? Would you do this?
