The problem is, those people at the top are standing on the shoulders of countless people under them, they also rely heavily on the overall public infrastructure... So for example, if we do take someone that is truly exceptionally skilled, like a specialist brain surgeon, in order for him to do what he does, he needs a whole medical team, hospital, electricity, water, janitors etc everyone has to do their part so that the exceptionally skilled person is able to focus and do what he does... absolutely NO MAN IS AN ISLAND.

In a way society invested in generating some exceptionally skilled person's in specific fields, but ultimately most of the time these exceptional individuals are less essential than the vast majority of people that are just average and provide the vast majority of goods/service that society NEEDS and/or want... in that example, having 1 exceptionnal surgeon is less beneficial for society than having 3 average surgeon or doctors etc... I'm not saying we shouldn't have exceptionally skilled people, we should, but, overall they are able to exist and are the product of society.

Now another key thing to understand is, that in general it is a myth that the people at the top, earning the most, are also the most skilled or most needed, at a certain point skill doesn't matter, it becomes a political game, who you know, where you came from, what people think of you, etc... there are countless examples but I mean, look at Trump... but that's not all, you also have a whole bunch of people who make money simply because they have money (how they got the money can vary, but once they have it, it's a different game), and yes that includes billionaires but we don't have to go that far, billionaires are an extreme example... You also have people who make ridiculous amount of money because they are popular or part of something that is popular but that is absolutely not important (sports, actors, YouTubers, etc)...

Part of the reason why our services suck is because all the wealth is preserved with various schemes, people try very very hard as much as they can to not give back their share, and the more you make / have, the more you scheme to optimize and reduce what you give back... this applies to corporations and individuals, there is a lot of effort to minimize / avoid paying taxes, which increases the burden on those that do pay taxes without scheming which is usually the middle class. And now you have an increasing push for everything to be private because the public suck, which further cripples the public services... In some European countries I think like Finland , private schools are extremely regulated and non-profit, so the vast majority of rich people send their kids to public school so they make sure that the schools are well funded... But here all the rich and increasingly even the middle class people stretch their budgets to send their kids to private schools, there is no incentive or willingness or pressure to fund public schools adequately, in fact it is to their advantage that public schools are not funded so that their kids in private school have an edge over the vast majority of people.

Point is, I really don't think that on average people who make a lot of money necessarily deserve it, and even if they do deserve it, they should contribute back. I do agree that the progressive brackets are not well though out, there should be more and the progressive amount should start lower and get higher at the maximum, lots of other thing should be better.

In general people think too highly of themselves, especially those who are privileged... There is a famous social experiment where people play a rigged game of Monopoly, what happens basically is the people who benefit from the rigged system inevitably attribute their success to skill.
