That is a historical rewrite.
It is the wealthy and powerful who have, historically, rigged the game to not only remain so but add to the divide.
Given you are so wrong about this everything you build upon its foundation is fundamentally flawed.
All righty then. Let me give you a true-life example proving how humanity is, instead of some theories by academics who imagine that a world can operate where there is no class system, and everyone has the same with their being no poor people and no rich people. Firstly, you have to do away with the notion that everyone has the same work ethic as others and that a government can set the wages for labor. When a government does that, it creates worker shortages because a restaurant owner will not pay $50.00 an hour to cook or sweep floors and if he is made to, people then won't eat at restaurants because the prices are too high.
I worked really hard at MLM for about two years in my younger days. I built downlines by creating ads and web pages and studied hard, watched numerous videos, attended seminars, meetings, phone calls. MLM is like life. At the top are 1% of people. Near the top are 5% trying to be a 1 percenter. At the bottom you have 1% and near the bottom about 5%. In the middle is where the masses fall. Those in MLM lie through their teeth with ads that make people believe that you can be where they are with little or no work or by placing a few ads. So, what happens is the bottom tiers believe that and pay an entry fee and do little or no work.
Those in the middle so some work and certainly not nearly as much as the top 5-6%. They would dabble in it, talk it up to friends and relatives, study some and maybe make a few bucks. They hang on for a few months and then drop out because they find out that the promise of little or no work was a lie. The top 5-6% didn't want to tell them that they personally work 12 hour days, 7 days a week and only some of them make enough money to do it full time. They have to hustle, learn new ways to promote, sacrifice friends and family, be on the phone or computer all the time.
MLM is life. It's the way life is and works. Now then, suppose someone like YOU comes along and tells MLM companies something like, "No, no NO! This isn't fair. There should be NO people on the bottom. You guys at the top are taking advantage of them. I am passing legislation that makes you people at the top send 0% of your money down to the ones at the bottom because they are poor people, and you are rich and I am a champion of equity and fairness."
Whayt would happen is those people at the bottom would accept the money they didn't work for and demand even more. The people at the top would join those in the middle and not work as hard anymore because it doesn't pay. The MLM soon collapses.
Now, put Country in place of MLM and you will discover the problem with socialism and progressivism. The COUNTRY would collapse as has been proven the world over.
