Together they can have anything in the world, why does only one of them get that kind of life?

Because the one has a talent that 99% don't.
Because the one took a huge risk that 99% didn't.

Further, labor is one of the biggest expenses in any endeavor.
It isn't 50/50 split. Its more 99/1.

However, the entrepreneur is skilled with money management. So he doesn't waste his money.
The entrepreneur also gets 1 off of as many laborers as he can get. If he gets 100 laborers, he gets 100, while the laborers get 99. Even at this level, the entrepreneur gets richer while the average laborer gets poorer.

And the other half that we never bring up is that the entrepreneur often makes 0.

I believe that an entrepreneur is worth and worthy of all the wealth they create.
The entrepreneur skill is something that 100s of laborers can't even imagine doing.

(and believe me, i have tried. Tried to get the laborers to think bigger, to think of a business for themselves)

Now, again, i will reiterate that there is a 2nd class. One that we mistakenly call "the rich" and very mistakenly call entrepreneurs (because they run companies)

And that is the rentier class.

Banksters who take 8% of everything, everyone makes, every year.
And they use this money to buy up the real assets; the companies that entrepreneurs start.

So, every year the working class has less and less.
And they see that "the rich" (rentiers) have more and more.

Never realizing how the money is being stolen from them.

Especially since the workers were never taught about money.
They do not know money management.
Nor do they know of the evils of inflations.

So, we come back to the original phrase

It is a terrible charge, but it is true.
The wealth the workers have created, as a class, has indeed been stolen from them.
And they are being robbed in the same way every day of their lives, even at this very moment.

Every worker is then pointed at the entrepreneur.
Instead of at the rentiers who are actually stealing their wealth.

You may ask yourself. Why is there a stock market?
There shouldn't be such a thing.
Anyone who understands what they have, as partial owner of an actual asset would never sell it.
