...you must not know many people then. There's lots of opportunity for a middle class life in non-it-related professions. Something I found pretty shocking after I left the sv bubble.

Such as?

Marketing, sales, numerous supporting jobs in entertainment, skilled trades and engineering, (as many mentioned) white collar food industry jobs, logistics, accounting, statistics, mediation, community builders, I could go on and on. So many diffierent types of jobs, even when you exclude all the shitty ones that make the world a shittier place, like low-information political shills and propagandists, (tiny conservative talk radio shows and online communities do decently, moderate and liberal not so much) junk and junk food marketers.

I would imagine any engineer or someone who went through trade school. Maybe they don't make enough to be considered middle class?

Many trade school disciplines.
