John,
If you know VB, and you are faced with getting $125/hour for a VB job and $80/hour for a VFP job - and making the timeframes equal and the type of work - the guy who picks the VFP job over the VB job is not only an idiot - he is a lousy business person...
Just as the person who picks a $35-50/hour VB job over an $80-100 VFP job would be an idiot and a lousy business person. It works both ways. And, yes, I have seen that spread here in Atlanta recently.
There are higher-priced VB jobs and also lower-priced VFP jobs here too, but your above statement is just a little too slanted for me to let it pass. :-)
