Consumption is good, actually.
If people actually stopped purchasing goods and services we would find ourselves in a depression and tech jobs are far far from the last to cut. Seems people didn't pay attention to the v in their macroeconomics class.
If people don't spend it on things they actually want then the government has to step in and spend it on things they think people want and I assume folks intuitively grok that keeping the central-planning of the economy to a minimum is a good thing. Anti-consumerism can be a good thing for you as an individual or family but it's a virtue that is only afforded to you because most people don't join you.
Perhaps I should have phrased it differently.
Seems like you might be approaching this from a different perspective / this is a confusion over the mutual meaning of words. But the GP is basically a slogan or an axiom, not worthy of serious rebuttal.
