At the risk guarantee of taking a meme too seriously...

Buying, rather than saving, is how the rich get richer. They buy rentable assets. The value goes up faster than a savings account, and they have the added bonus of turning a profit along the way too. Even a company is basically a rentable asset. You pay for the privilege of using the company to make money for yourself.

If consumer activity stagnates, it's not really a threat to the rich. The economy just rallies around servicing assets instead. And putting your money in a savings account doesn't keep it out of the hands of the rich, either, cuz who do you think benefits from the loans the bank makes using that money?

"Now, why don't you save
All the money you earn?"
If I didn't eat
I'd have money to burn

Hallelujah I'm a bum!
