You have any real-world examples, or is this just a feeling?
A wealthy person puts their money to work in the stock market and other investments.
As their wealth increases due to gains in their stocks and the rest of the portfolion, they don't pay a penny in taxes on those gains until they cash in.
The capital gains tax is less than the income tax.
Nevertheless, there is no reason to ever cash in those capital gains.
Instead, what wealthy people do is borrow money, using their portfolio as collateral.
They never have to touch their gains.
Here's the really sick part. The interest rates the uber wealthy are charges is a LOT lower than the rate you are charged. A paper billionaire is charged one percent or less for a loan.
They can buy a mansion with the loan, and deduct the interest on that loan on their taxes. Or they can buy a piece of art. Or your company. Or whatever they wish.
Whatever they do, they will make more money than they owe in interest.
This is what rich people do. Over and over until they die. Never touching that original portfolio as it explodes in value.
And there are all kinds of tax loopholes which enables them to pass on their wealth to their kids.
And guess what? Since the kids inherit the money, their capital gains starts at ZERO!
And now the kids get to play the game from scratch.
