The whole problem is that they raise the prices of something all people deserve.

A home.

When landlords can get credit and buy two houses to rent out, they have raised the prices. They could outbid someone else because they had both rent and maybe a job to live off. Soon it's a company that owns a building, and then they own a block. Every time they outbid someone who wanted to live there they raise prices.

And then there is rent pricing. See landlords could set rent low, but they might have taken credit that wouldn't work for that, so that they could outbid. Instead they can price it for what they can get. In the marked, and raise prices accordingly.

The price gets inflated more when you have big companies that own a lot, they often own enough that they can let flats stay empty (which they do). This is to keep prices high. Just check their stock price, juicy isnt it?

See, this is because the banks and private investors have invested in property. And they expect a profitable return, and that return has to increase every quarter. Rent prices can't go down, that would lover the stock price and could lead to a lack of investment which would not just tank the company but cascadingly the housing marked and so the banks. This would especially fuck mortages and people wjo own them as you're trapped with debth and a valueless home.

But look at 2008, see who got bailed out.

Be thankful you've got the privelege to be ignorant 🤷

There is a reason why economists call the act of syphoning value from the economy without producing anything rent-seeking behaviour. Allowing private interests to profit from basic human needs is a very inefficient way to fulfil those needs on a population level, and in many cases promotes the forming of dynasties, and the concentration of wealth.

There are few sensible reasons for a society to allow ownership of living space far beyond what the owners can use themselves.
