Timeless lesson. Always beware of a politician coming to power promising free stuff. It never works out in the best long term interest of the people/country. There are no magic tricks in this world, things have to be earned and paid for. Hopefully citizens of the west learn this sooner rather than later
Because you, know, it just doesn't work. And all of the positive experiences with socializing certain public goods in liberal western democracies are just a magic trick.

You realize that Russia was a society of serfs, all the way up to the later part of the 19th century, right? The aristocracy quite literally owned people, by virtue of owning land.
Their wealth was built on centuries of theft, violence, and repression. And then, they turn around, and say: "It's your problem that you're poor, hungry, landless, and are fighting in a pointless war."
