Trades are recession-proof though. Rich or poor, recession or not, people still need to shit and don't like doing so in the dark, so at least plumbing and electrical will still have work. People need housing, so anything construction and building work will also be fine. Same for heating and HVAC.
The fields mostly impacted by recessions are those that never had a business in the first place - lots of tech has been built on "growth & engagement" freeloading off VC money with no actual businesses paying for that "engagement", and now the free money ran out.
They're certainly not recession proof - recessions are terrible times for trades. Trades do well when the economy does well - people spend more on non-necessity projects and that demand goes away in recessions. Sure, people still need a clog removed - but now there's more plumbers because they aren't installing new bathrooms.
It really gets old hearing software developers talk about trades yet none of them do them. I've seen what the trades have done to my dad, uncle, grandparents. They earned good livings - but it was real, hard work, and they paid for that hard work.
