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.
