The point is, you don't get it Dave...
Usefull skills are great in a good or normal economy...When your economy is going down in flames it don't work too well...
Ya see in collapsing economy, few are building homes, that means few are buying washers, dryers, furniture, new cars...Fewer contractors, wages are stagnant so few are buying anything they don't need....Few are creating new businesses, credit cards are not being used, the need for accountants and loan people are way down, real estate agents are starving...BTW, all the labor intensive jobs are given to illegals..Like HVAC, truck drivers, warehousing, what is left of construction etc, etc.
This is not a difficult concept to understand Dave.
Now, they're might be demand if your repo men or bankruptcy attorneys...
For those that want to be doctor...Good luck affording 100k for school and this health care system...
Neither is it difficult to understand that, when the situation changes, the definition of “useful” also changes.
