I personally define middle class as the people with most of their wealth in the form of their home. So yes traditionally those people would be considered part of the working class as you say. I don't disagree. (My division is supposed to reflect how those people do behave, whereas the traditional Marxist one is supposed to be how they should behave based on the real relations behind the smoke and mirrors. That's fine, different categorizations for different purposes.) For the second part, well, we'll need to abolish SFH zoning and related things, which is very unpopular because it would undermine landowner's speculation in the short term! (It's especially annoying because taller buildings would lead to more valuable land area in the end, just cheaper floor area.) So nevermind there are efficient market-based things to do, like everyone rents land from the state at auction which pays out universal dividend. Our land markets are popular precisely because they are a speculative mess!
