The majority of the fabulous wealthy play capitalism as a zero sum game. For them every dollar you are poorer is the same as them being one dollar richer. As they have won the game I would say that they are correct and you are not.
It's more like every 100 dollar rich people make, someone around them(their employee, their shareholders) makes one dollar with them. But they are still making money.
A big company can have tens of thousands of shareholders. That's a lot of people making money with Bill Gates.
Business is competition, sure. And some people may lose money in the field of business if they lose the competition. You
always have the choice to not participate in running a business and just work as an employee, buy stocks of winners in the market (like google, Microsoft or SP500) with your salary and make money with them.
I would say even if capitalism game losers exists, the winners still greatly outnumbered the losers. Otherwise you'll see more people in poverty than middle class in a country with successful companies and good economy. But that's clearly not the case.
52% of people in the US are in the middle class, 19% in upper middle class v.s 11% living in poverty.

The large amount of people successfully become middle class via capitalism is already enough to justify the existence of this game
As they have won the game I would say that they are correct and you are not.
I didn't lose the game, as I didn't live in poverty. According to data 71% of people who played the game has successfully become middle class or higher and I am one of them.
