I mean it's estimated that 1/5th of Russians have no access to indoor plumbing.

This is a country where its leader/president/dictator/mafia don/caporegime is quite literally a multitrillionaire.

Russia asking for sanctions relief is just relieving pressure for Putin as the people who keep him in power (the oligarchs) need access to the money they've stolen and want to be able to buy more yachts and football teams. Putin and his circle, as well as the oligarch class, don't give a fuck about the average Russian.
