But it actually creates new wealth which service ‘industries’ mostly do not.
Factories create wealth and services don't? Reminds me of the story about the visiting preacher's telling the man what a nice garden that him and God made. The guy replied that the garden looked a lot better now than back when God was doing by Himself.
I need to tell you quick (before I get hit by lightning) that factories do a lot better when they first get the right patents, efficiency studies, good transportation, a top notch sales force, and oh yes --investors.
all wealth is created by engineers and their services and companies
Of course it does. All the "trades" are services. The plumbers, carpenters etc exchange their "services" for cash. Does a completed house have more value than a pile of logs, and a load of plumbing and electrical supplies?
The architect, excavator, carpenters, electricians, plumbers, dry-wallers, landscapers etc did not simply get together and build that house just for fun or...
OUT OF THE GOODNESS OF THEIR HEARTS!
