With so many living in rental properties with little "real property" going by tax liability would be the only practical method.
Look at how many people today own little to nothing. They either rent, or else are paying nothing but interest on a mortgage, and don't have enough equity to break even, after paying the real estate sales commission, and come out of the deal with anything if they sold. For example, several lending institutions are right back to lending money with as little as 3% down with marginal credit scores. If they had to sell shortly after the sale they couldn't pay off the loan, because the commission is usually 6%+ after title insurance and other sales related expenses. This is what crashed the housing market in 2008. "No skin in the game".
Most lease, (rent), their cars. And lately many are "renting to own" their home furnishings because they have no money to purchase them, and their credit is damaged, or all used up. (Places like "Rent-A-Center" and "Aaron's" cater to these types). Subtract the credit card debt most have piled up, and if they were to attempt to liquidate their assets and pay off their liabilities, most couldn't do it. They would be homeless in the street owning nothing but debt.
Now put these idiots into a voting booth, and who's handle do you think they're going to pull? They'll go communist every day of the week, and twice on Sunday. This is irreversible because the most difficult thing any person can do in their lifetime, is to accumulate wealth in any amount that allows them to be financially independent. Without receiving any government assistance. Today we've got over 1/3rd of the nation in this position. (105 million+ people). Sooner or later the bubble is going to pop. The only thing idiots can do well is destroy economies because they are all take, and no one gives. And as long as the communists believe the top 1% can support the remaining 99%, none of this foolishness will change.
