Blue-collar workers in non-standard fields tend to earn more

doing aluminum alloy, applying films, caulking, air conditioner repair, paint touch-ups, and so on.

As long as a process can be standardized, you become a replaceable cog—you can be swapped out for cheaper labor or new hires, or even replaced by machines. Since it’s a standardized workflow with fixed procedures, it’s naturally programmable and scalable.

Blue-collar technicians charge you fairly. What they’re selling isn’t a fixed routine, but on-site solutions—customized approaches tailored to the situation.
