It’s not about “cash at hand”, it’s about who owns “stuff”. In days past people knew that the aristocracy owned them, their families, the land they work, and the output of their work by a God given right flowing from the anointed King. It was easy to see too - those people living in palaces up the hill owned everything, you owned nothing.

It’s more hidden now. We all have rights and freedoms and whatnot. But there are still people who “own stuff”, and people who don’t. With shades of gray in between those two extremes. It’s good to be cognizant of the system you inhabit relative to what has existed throughout history so you can make good decisions and position yourself accordingly.
