Just a thought

It all depends on where you live.

In some parts of the world, everything is corrupt. "Politicians" are not elected in the real sense of the term, and people are truly exploited. Businesses are not created, they're handed over to corrupt loyalists and "entourage". People have every reason to be resentful, as they have no choice in where they're born. Their misery is an accident of birth.

In some other parts of the world, where they have authoritarian regimes, and the government runs everything, China for example, there is a level of equality, and all the worker bees are taken care of, in return for being good worker bees. Income inequality, however, is massive and a tiny minority is in control of everything. In a way, another accident of birth in who gets what.

In yet other parts of the world, business leaders understand that they do not create businesses. Their workers, engineers, etc. create all this. They accept a more reasonable tax situation, where more of the money is poured back into the system and that lifts everyone up. Western/Northern Europe is an example of where income inequality is less of a problem. People are happier with good healthcare, good education, good services, and politicians who answer to the people (relatively more effectively than other places in the world).

Then there's the United States, where equal inequality is massive. Some business leaders understand that their power comes from the people who work for them, and some think they're Gods. In fact, Amazon is what it is, thanks to all the workers. Bezos is not filling your order, or writing that face recognition software. There is massive income inequality, among the worker bees. Engineers are buying $8M homes, paying cash, and warehouse workers live in crowded apartment buildings. In this system, business leaders do not pay their fair share of taxes and while some may think it's a level playing field, but it's not. Gates's high school tuition, was enough to feed multiple families in Seattle.

People have the right to be upset about income inequality. They also have the right to complain about political systems, rigged to keep the rich and powerful in control.

A bit convoluted but I think I see what you are saying.

People have a hard time excepting the fact that there are people out there who are doing better, in some respects, than they them selves.
People now days seem to hate rich people. They think that rich people owe them something because they have what everyone else wants.

We can't all be the captain of the ship. Someone has to shovel the coal.
Also... I have never collected a check from a poor person.

If this post were written 400 years ago you might find someone agreeing !

But the current people running the world didn’t plan for the economy !
Thus they failed everybody !

Business isn’t interested in anything other than making money.
They have no interest in social or economic advancement of people.
Hell they don’t even care about their workers safety at work anymore !

If governments and corporations really cared about people laws and rights would not be needed.

Because as we drift towards socialism, the masses want equal outcomes, not equal rights or equality.
