Russians can't get car parts, coke, McDonald's or Levi's the simple things they have taken for granted for the last 30 years.
Spit in the ugly face of whoever told you that. ;) The real problems with parts began to appear only in the luxury segment - and people are frankly laughing at moneybags who put parts from auto junkyards on their cars. Moneybags are not really liked here in general and when the money they've pocketed stops solving their problems immediately, it gives the feeling of being pleased with justice. ;) There are no problems with spare parts for mass-produced car platforms, Asia is rubbing its hands together happily and counting the percentage of sales growth.
As for the hostile atmosphere abroad - we do not care about it on a mass scale. Millions of people have discovered that in Russia itself there are so many interesting places to visit that life is not enough. And behind the demand begins to grow the market for hotel and other local tourist services. New jobs, some in previously rather depressed regions, where apart from natural beauty, little of the benefits of civilization was available to the local population.
McDonald's is now called "Delicious. Period." Two problems do exist - you have to remember the names of analogues of the old burgers (but salesmen will tell you if anything) and there is no exact analogue of the Big Mac. There is a close one, but the mayonnaise taste is a little different, I can feel the difference. Otherwise it's the same as before.
There are piles of Turkish and Russian jeans and other clothes everywhere, I would not say that in the close price segment they are any worse than the world brands in terms of quality.
As for smartphones and other electronics, no problem, unless you belong to a faggot subculture that expels everyone except owners of the latest iPhone model as to "two week ago" date. ;) See above about situation with luxury car parts to understand how masses react. ;)
The Russian economy will completely collapse when the stock markert is open for foreign investors to pull their money out.
I suspect that solution will be simple as shot. Locked Russian assets abroad will be exchanged to locked foreign assets in Russia. One to one. Just like POWs exchanged almost every day now. ;)
Poles are beyond repair.
But not beyond recycle... ;) Experiment is already started on Donbass, especially in Ugledar direction where is hard to hear ukrainian language in VHF/UHF comm bands, only english and polish.
