People don't want to subsidize first time homebuyers, but they have no problem with the government subsidizing landlords (depreciation allowances, tax deductible mortgage interest). After so much distressed property ended up on the market after the housing collapse, private equity money swooped in to suck all the property up and charge "market" rent.
Millennials either need to adjust their expectations (get remote jobs, not be tied to areas with high cost of living that are going to extract a large part of their income from them) or fall into enough money to not only buy a property, but to weather any financial disasters they have so as to not lose their equity by losing their home. Hustling hard for years on end while being frugal is another option, but it is no guarantee of success.
