Did he mention that a lot of the real estate that people own in most post-Soviet countries is inherited when (grand)parents die, this being first if not the only step towards the market for most people?

None of the people I know from Russia, Kazakhstan, Ukraine and Belarus bought their first apartments on their own through hard work or anything: it's mostly apartments where your grandma died, apartments that you're either massively helped with or outright gifted by parents when yuu have a significant other to move in with (so both families join funds, most coming from selling some dead relative's apartment) or on a wedding day (a rarer occasion), or some mix of that.

Without any help or gifts, you're lucky to be able to get a mortgage that you can pay off before you're 60 (at least).

The real estate prices outside the US and the EU may seem nicer, but salaries and expenses sure don't.

Everybody is screwed, everywhere.
