If you're finding it hard to make ends meet lately, I'd say investigate whatever income-producing possibilities there are for _Wall Street_. If you're doing okay, then, yeah, donating it to the public at large could not only help "the class struggle," but your reputation -- which, in the end, could be used as a kind of bargaining power for your next work. Not to mention that donating it could really enlighten a lot of minds and educate a lot of folks.
You only know what your financial etc. straits are, though. That should take precedence, imo.
