If AI replaces workers to cut costs, who is left to buy the products?

I keep seeing AI layoffs discussed as if they are only a company efficiency issue. Company replaces workers with AI → costs go down → margins improve. That makes sense for one company. But I’m stuck on the bigger picture. Workers are not just “labor costs.” They are also customers. They pay rent, buy phones, order food, subscribe to software, travel, invest, and spend in the economy. So if many companies start replacing people at the same time, doesn’t that also reduce the spending power that businesses depend on? It feels like every company is thinking: > But if everyone does that, we may end up with: lower labor costs, fewer people earning, weaker demand, and eventually lower sales. So the question I’m trying to understand is: **If AI becomes good enough to replace a large number of workers, who exactly is supposed to buy all the products and services being produced?** Do you think this is a real risk, or will the economy adjust the way it did with previous technologies?
