The reason that you have less than you used to is because they have more. Do you understand?
You are on a planet of finite space and largely finite resources. If you let rich people have more, then you will have less
If you have a pizza with 7 slices. And a rich person takes 6 six. That leaves you with only 1? Why would you allow such a silly thing? Possible because you're the sort of stupid idiot who would slice a pizza into 7 slices to start with
The only thing for you to do is to take what the rich have and redistribute it to the poor and working class. You need to implement socialism or else "you will own nothing". This means voting for the farthest left politics you possibly can and not letting yourself get sidetracked with racism and bigotry identity politics. Because these ARE the means they use to control the lower classes and get them to vote against their own economic interests (note: for their own enslavement)
