They guy did his research, and he did it right. Even mentioning the "social contract", that's not something you hear from an average youtuber.
There's only a few things I've noted
Although the monthly rate can be calculated as yearly÷12 and is acceptable, it is inaccurate. Doesn't change much, but still. ( (1+monthly rate)^12 = 1+yearly rate <= this is the accurate conversion)
Next is "failed pension reform." It's failed in political sense. The intent of it was to temporarily lessen the depletion of pension fund, which it technically did do. But, yeah, it was absolutely not popular. Not to mention that it didn't solve the root of the problem, which was obvious from the start. Back during his first or second presidency period, he promised not to raise the age for retirement, yet in 2018, he did exactly that. Needless to say that his ratings have been falling ever since then and up till February of 2022.
The one thing I would've liked him to also mention is "quality of foreign exchange earnings," which is a relatively new term. Essentially, companies now need to pay attention to wether or not they can exchange earned currency for something that they can trade with other countries or within Russia. Previously, they traded in dollars, so it was never an issue.
They may not matter in a sense that you can't elect anybody but Putin.
But they do matter in a sense of showing the incumbent they aren't stable.
After successful re-election of incumbent, they fall into a sense of euphoria. This leads to creation of some absolutely horrific and unjust laws.
However, when the re-election is deemed unsuccessful (say 55% voted for "the right candidate", but the second place got scary high 30-35%), they become timid.
That's how informational autocracies work. And that's why elections there absolutely do matter, as they directly affect quality of life. It's the safest and loudest way of showing the government your middle finger.
