Mon,
It's certainly a problem, especially in the VFP domain where the market is mature and many of the best developers are completely settled. In dotNET it should be easier, except that the level of change and newness makes it difficult to distinguish between an excellent developer who is finding their way and somebody absolutely hopeless who can probably get away with poor delivery for as much as a year by blaming everything on .NET's newness and complexity.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
