I have a feeling that many low barrier jobs will end up being stuff that is either dangerous or morally gray (I forsee a booming market for sex work for example). So a lot of stuff that people wouldn't be comfortable with minors doing.
You didn't specify, do you think it is a morally white area? or a morally black area?
Better yet let's move away from colors. Do you think sex trade is immoral?
I'm genuinely curious because it wasn't obvious form reading your comment - and I'm not sure I have strong feelings one way other the other and so it would seem to me to be the epitome of a "gray area"
