Earlier quoted context omitted.
doesn't really matter. as I just wrote, my only point is that the supply at that price is greater than 0 - that some people will do it. who are in their twenties. you won't find someone even over thirty willing to do it though. it's a descriptive statement.
Are you sure the people that will do it are the ones you want to be doing it (if you are paying?). If they are so vastly underestimating their market value, perhaps it's because they are actually vastly overestimating their ability.
I have to agree with the perhaps inappropriately named logicallee. And I'd go further - it's not just a matter of age, nor (as others in this thread have said) of inability or stupidity, if someone works for a salary under market value. I am far from the best at my job in the world, but I'm ok, and for the longest time as a freelancer I charged way under the market (in fact I suspect I still do, though not so egregiously). This was - I think - not because I "overestimated my ability" or anything like that. I was simply not a business-minded person. I was afraid to ask for more. I earned enough to live from, and the rest seemed somehow distasteful to me. I'm not saying this is the ideal, just a fact. And if I have these characteristics, perhaps others do too.
