It comes down to specific skill sets. In the next 20-50 years, if your job can be replaced by a machine, it will. My company recent moved from truck drivers to autonomous trucking. Each of those non educated truck drivers used to make $250k, that's hundreds of jobs gone and millions saved.Previous studies in NZ showed that a university graduate was more than likely to be more than a million dollars better off at the official retirement age than someone that did not attend uni, but this is becoming less certain with more and more unemployed or under utilised graduates.
One of Australasias richest man was a tow truck driver and later studied for a business degree
Nz'der Peter Beck the founder/ CEO of Rocket Lab only went to high school but must be a pretty persuasive talker to get U.S. firm Khosla to back him
and sometimes there is luck
An acquaintance of mine who became stuck in NZ due to border closures over covid is on a couple hundred thousand a year to weld railway tracks together. He was offered the job without the need to produce a CV or go to an interview as he was the only person in NZ who knew how to weld railway tracks in a certain manner.
That's flabbergasting because we have tens of thousands of migrants from China and we can't even find one who knows anything about welding railway tracks.
It's rare for any worker to have a very specific skillset in high demand, but if you have it, can command a high salary. This applies to university grads as well, just those that are highly educated are more likely to have the skillset employers are looking for.
Only way to get really rich is to start your own business and put in the hours.
