The time needed to get $1 in international dollars is 63 minutes in the US. This is about twice the average in Germany, France and the UK according to an Oxford University researcher. This suggests that average poverty is significantly higher in the US.
Commercial scuba diving is difficult to get into but it doesn’t take many years, and for sure nowhere near as long as becoming a doctor takes.
But I get the feeling you are just trying to argue for the sake of arguing and this has long moved past the original point.
I just emphasized what the original point was and how my argument was connected to it. You just chose to ignore that.
It is completely beside the point how long it takes exactly to become a offshore scuba diver or a physician. (Where I live you need to have at least a three-year vocational education before you can start commercial diving training at all. I’d estimate it takes you about four to four and a half years all in all. Becoming a doctor takes six.) The point is that both are jobs that are difficult to get into and require specialist training. They are not “unskilled” labour, the kind ob jobs the original argument was about.
