Economics is absolutely a valid field of study.

Economists are also mostly employed to serve the interests of the rich. They are a primary source of the useless metrics we hear on the news that truly reflect only the experience and interest of those who have enough money to respond to that info.

There are many other methods developed by non-shill economists that we never hear about unless one goes digging into more obscure academic literature.

The Gini coefficient is one example. It is a perfectly valid way of framing and interpreting economic data, but one almost never sees it in popular media. Why?

The people that buy economists and media don’t even want to have the conversation about income inequality.

So, yes, economics is a valid area of study that has some valid methods.

Also, most economists are intellectually dishonest and compromised shills for entrenched wealth.

Two things can be true at the same time.
