Dipshits like Musk and trump will take loans out on capital gains, and pay off the interest from older loans with them (and live on some of it,)
It’s why the stock market is so important to all of them. They need their assets- stock shares, private companies, real estate- to always go up.
The reality is though that people that do that are over-leveraged and have near-zero net worth. Which is exactly why Trump is having trouble securing those bonds.
