Since when did money become everything?

In the past, getting into public service, academia, or the media earned you quite a bit of respect, and the power of one's educational background seemed relatively strong. But these days, it feels like people's mindsets have shifted to the idea that money is the only thing that matters.
What exactly has driven people to become like this?
1. The real estate surge during the Moon administration
2. The stock market craze
3. Social media comparison culture
4. Individualistic culture caused by COVID-19
5. Other??
