Nothing is wrong or broken.
Have that other 90% start and run their own businesses or go to school and get a degree in business that allows them to become a C level exec or invent a product and launch a startup.
90% of the people on this planet don't do SHIT. Because doing shit is HARD. Most are content working for someone who's willing to take risks, often with consequences to their own personal lives.
And that's OK. There's nothing wrong with that. Not everyone can be an entrepreneur or C level exec. Most people prefer simpler life.
For nearly a decade I lived across the street from a retired fireman. He put twenty years or so on the job and retired with a very generous pension and full benefits, for life. I watched as he amassed RV's, boats, jet ski's, Harley's, cars, etc. Living the life, as they say.
At the same time, almost everyone on the same block got up at five or six in the morning to go to work every day. Office workers, customer service folks, a couple of engineers, a couple of doctors, I know them all. And, in my case, well, it was 18 hours a day 7 days a week in the garage working on developing a product. For two years the external view was that I didn't have a job or didn't go to work, when, in reality, I was doing the equivalent of five jobs and was working every waking hour.
So, a couple of years later the product launches and it does very well. Seven figures per quarter very well. I decided it was time to replace our two cars, which had nearly 200K miles and were in bad shape. When the two mid-range (nothing fancy) cars appeared on my driveway the comments I got were, well, incredible. "Wow! You must have won the lottery!". "Dude! Did you rob a bank!". "You don't work, how did you buy these cars!". "Are you a drug dealer?".
Nobody EVER made a comment about the fireman being set for life when he did not contribute a dime to his pension plan that paid him six figures a year and his gold-plated health plan. No, the entrepreneur was the "drug dealer" on the block.
I created dozens of jobs through an incredible personal effort and sacrifice and somehow didn't deserve what I had. I was compared to the 99% purely based on my wealth.
Funny how everyone sees people who make money as undeserving purely based on how much they make yet have no clue what it may have taken to get there and can't be bothered to ask.
Please stop this nonsense of comparing the N percent to the M percent based on how much money they make or have. If you are going to do that, include HOW they got that money and, in particular, WHY the M percent couldn't be bothered to even try to do better, educationally or in business.
Hint: You are not going to become wealthy working at McDonalds or, in general, working as a employee at 99.99% of companies. The only corner case being joining a startup that goes public and your stock options make you wealthy. Like I said, corner case.
It's funny how people who often make the argument for this unfairness have their brains short-circuited when you ask them if it was unfair for Steve Jobs to become incredibly wealthy or, to use someone who's around today, Elon Musk.
