A teacher (unless in the public school system) doesn’t make enough without some shver support, but OT/PT can with a big enough work load, and there are other jobs which do better and are becoming increasingly popular. Computers is one thing that comes to mind.
I grant you that I’m not familiar with the “computers” job market, but other than a code monkey (which doesn’t pay), how much can someone make without being a real professional (which means going to a real college, etc.)? Also for OT/PT, how heavy of a workload is possible with the expectation of children? I have not seen that OT/PT/Speech is an acceptable alternative to Shver support, but we may see it differently.
