In a moral and philosophical sense, even the poorest man has a vested interest in private property as a moral concept. Even the man who lives out of his car has the sacred, individual, inviolable right not to have it ripped from him, and to be secure in its confines.
I'm not sure why you think this is less true for the rich than for the poor.
Everyone likes property rights but only the rich would be motivated to live in a world where stealing property is possible? That just doesn't compute.
Wait a second here, what's the dollar value of a 700 billion dollar loan?
Value to who? To the recipients of the loan? To the government who issued the loan? To the overall economy?
The financial bailouts were not done for the sake of the banks. They were done for the sake of the entire economy, you, me, bankers, everyone.
And the value of a loan can, in fact, be quantified. The value of the TARP loan was probably a few tens of billions (I don't have the exact numbers in front of me), hardly a sum that approaches the amount of money dolled out every year to the poor.
Unprecedented and massive as they were, the TARP loans
still do not come anywhere close to justifying your belief that the rich take more from the government/taxpayer than the poor. You're still off by a few orders of magnitude.
