I wouldn't be surprised if that was the perception from within Russia, but I also doubt it's the case empirically and objectively. It was proobably good from 2000 to 2013 under Putin and then Medvedev, who was probably Putin's puppet president.

But now, their GDP per capita is stagnant, if not in decline while their population is decreasing, and their GINI index is similar to that of the US and China. That's a really bad combo. I can't imagine how quality of life would be improving under those conditions.

Having said that, there are better metrics like median salary and median household income both adjusted for purchasing power parity, but I haven't been able to find graphs for those. In fact it was kind of hard to find consistent economic data in general, which is another concern, but not really evidence of economic problems in and off itself.

I believe they're living like it's business as usual, but I'd attribute that to hypernormalization more than improvement in quality of life.
