This is the fixed pie policy, which assumes there's a limited amount of wealth to go around. And therefore, any time somebody gets "too much" of it, the conclusion is they must be why others have less.
This is not true.
And it's important to understand that it's not true, because understanding a problem is the key to helping solve it.
In pre-agricultural times, the average person was lucky to own a few dozen items. Today, the average person in a developed Western country owns a few thousand goods. Western households possess over 100,000 goods on average. There's vastly more wealth than ever. Especially if you multiply these numbers by the massively expanded population of Earth compared to prehistoric times.
Therefore, it's necessarily the case that wealth can be created and not merely stolen or shared.
OP is talking about "share of the world's wealth," not a fixed pie. While the raw amount of wealth (the pie) in the world does grow, the important measurement is what percentage of that pie is captured by the rich. And the rich are capturing an increasing percentage of the growing pie. That's where the inequality lies.
In a world of two people, where today I have one piece of bread and you have two, then tomorrow I have two pieces of bread and you have 10, I am worse off.
You're responding to the words "grab" and "take", and leading up to an argument in which wealth is created, by a Great Man, who deserves the wealth and power that He created, or else He wouldn't have incentive to create wealth?
People can collaborate to create wealth that they share.
The problem is when someone says "I am so great, that I deserve more wealth and power than other people".
Because of a bad experience in kindergarten, or because their parents told them that.
While that's true, there's still enough "fixed pies" that inceasing inequality does make people worse off. Land, attention, positions of power, etc. will all be taken by the wealthy, because only they can afford those things in an environment of high wealth inequality.
This counter argument always pop up and is getting stale.
The comment you replied to made no such argument, that the pie is fixed.
And you can look up how big slice of the pie the ultra rich are having…
I don’t understand why you are bringing up pre agrarian society.
