Progressive taxes are a way to make up for the imbalance of poorer people spending a higher proportion of their income on essentials, it’s a fundamental of economics. Although I have heard that the tax brackets in Russia are completely flat (not that that makes it any better).
The logic behind doing more, working extra, going to university, starting companies and all of that is to make more money so you won’t be just surviving. Taxing that people an higher percentage just because they make more money is effectively punishing people for their hard work and telling younger generations that they shouldn’t work very hard.
Look the issue here isn’t that you’ve people making more money - those people should actually be rewarded for it, because making more money means more contribution to society - but that there are people making less than they should / is feasible to have a comfortable life in modern times. I would rather fund initiatives to improve those “poorer people” life’s than this.
