Well in my case, it was worth it. I couldn't (or anyone else could either) get my current position without a MHA.
However, I can't speak say this applies as a generalization everywhere, but here in S. FL there are not many careers for people once they graduate from college or for those already possessing degrees at the moment. At least in some fields. Healthcare will always be there. That is pretty recession proof for most careers in it. But engineering, IT, business, Finance, marketing, etc... forget it. (refering to S. FL)
Not saying that it is worthless, in the future the economy could support those fields again so that jobs are plentiful again. But from what I have seen personally from first hand accounts of my friends talking about kids and siblings and such... most are indeed hitting up the vocational school for a year to get employed in a trade/skill area and then pursuing college afterwards at a slower pace. No sense in going full time and finishing sooner if you only end up unemployed sooner.
And especially with people out of work. They don't want to spend 2+ years going back to college (even though the state will send them), because they simply can't wait that long to generate income again. So they do the 10-12 months thing and reenter the workforce.
