This is not correct.

Wealth isn't a pie that can only be divided up into so many portions, and that "the rich" have a bigger slice.

"The rich" don't become wealthier by making their slice bigger and bigger while everyone else's slice gets smaller and smaller.

Instead, "the rich" - and everyone else - become wealthier by making the pie bigger.

Then, the slice of pie owned by the rich gets bigger, and so do the slices owned by everyone else.

How?

Simple: Wealth is created.

Imagine a plot of land. Let's say it's 1/2 acre. Let's say you bought it for $50,000.

Now let's say you buy $50,000 worth of building materials - lumber, concrete, drywall, shingles, roofing tar, nails, etc.

Further, let's say you buy $50,000 worth of labor. That is, you hire a team of workers for 2 months of their time. It's important to note you're not buying the workers; rather, you're buying their work product: their labor.

So, on that 1/2 acre of land is $150,000 worth of land, labor, and capital (the materials).

Fast forward 2 months. Nothing else of value has been brought onto that job site, and nothing of value has left that job site. The workers themselves have gone, but that's not what you bought - you bought their work product, which still remains in the form of a completed house.

So now, on that 1/2 acre of land stands a nice new house. Which you then sell. For $180,000.

$50,000 of land, $50,000 of labor, and $50,000 of materials. Now worth $180,000.

Where did that extra $30,000 come from?

That is where wealth is created.

Value (wealth) is created by turning raw (or basic) materials (land, labor, capital) into desired goods and services.

Ergo, that $150,000 pie just got $30,000 bigger.

"The rich" (in this case, you, the builder) got richer by $30,000. You didn't take that slice away from anyone else: you made the pie bigger.

And "everyone else" (the workers) got richer by $50,000 by supplying their labor.

And the suppliers of the building materials got richer because they made their pie bigger: They converted raw materials into the building materials that you bought - so their extra margin of wealth creation was baked into that $50,000 that you paid them.
