So you want my tax dollars to be taken, by force, and used to buy a house for someone who has no investment in the home at all?
No.
Let's say, for the sake of argument, that you could buy 582,000 houses for $150k each. These would obviously be little shotgun houses or the like. But liveable.
That would cost the tax payers $87,300,000,000.00. And the people would still be unable to pay utility bills, property taxes, maintenance costs and other expenses.
$87 trillion dollars of money taken from people who earned it. And unless you address the drug addictions and mental health issues, all you would be doing is moving the homeless problem out of sight.
