These concepts are all interlinked. The idea of social mobility is that people change their socioeconomic status over time. This includes their work and housing. It's baffling how you're actually dense enough to quote an example from the study that I linked that echoes exactly the point that I've been barking at all this time, as some sort of win for you. My god, you're slow.

This example is there to clearly demonstrate how rent control worsens the housing crises by creating conditions that fuck over people in need. In this very example, the elderly lady's socioeconomic status has changed. She's no longer raising a family and she's most likely retired. She's all alone in a big unit that she doesn't need, she's literally only there because she wants to cling on to the controlled rent. But by doing so, she's clogging up the unit from households that are still large and need that extra space. This is bad for her because downgrading to a smaller unit would better suit her needs but she feels the need to stay in the larger unit even though it's unnecessary, and it's also bad because there's a large household out there that either doesn't have a house at all or lives in a house that doesn't suit their needs.

This has nothing to do with evictions, and everything to do with how rent control creates conditions that stifle housing opportunities for everybody. Mobility is an integral part of any functional economy because people and society aren't static, they're dynamic. Situations and circumstances constantly change, and there needs to be a system that's able to provide people with options that allows them to adapt to their current needs.

If your level of education is quoting something that you clearly didn't understand with such confidence then you're a lost cause. As evidenced by you ignoring everything else that I stated in my previous comment, again, it's clear at this point that you're ignorant, an idiot, or a bad faith actor... if not all of the above. Since you have no interest in being honest or accurate, there's no point in me continuing wasting time on you any further. You will forever continue to lie, deny, and cry. Therefore, this will be my last reply to you.
