If we taxed people based on the benefits they receive from the government, then the homeless would pay a fortune.
This is a comical simplification. The public and legal infrastructure in America overwhelmingly helps companies and investors make money. Where would UPS be without public roads? Where would Warren Buffet be without a stable legal framework for investment? That's not to mention the military spending that secures all of these fortunes against foreign aggression.
To claim that the poor disproportionately benefit from government spending is missing the forest for the trees.
This is provably and patently false. Homeless people don't have their good protected by the police, don't get fire protection, don't drive, don't get deductions for businesses, don't get inheritance from their wealthy, millionaire parents, don't get lobbying influence. The entire system is set up to the benefit the rich with a few social stability benefits for the poor, which in turn keep them from uprising and storming the gates of the wealthy.
