Where to even start with this? Homes occupied by renters are not being "hoarded." At most this is a concern about homeownership rate, which is not nothing, but a distant second to whether people have places to live or not. Because rents are tethered to incomes, the rental market is a relief valve for speculative excesses in the ownership market. That's why it costs less than half as much to rent as to buy the same property in San Francisco right now. Landlords are not getting a return from collecting rent, they're getting a return from appreciation due to scarcity. And the more concerned voters get about capitalism and inequality, the surer a bet that scarcity becomes.
