Other than healthcare, what field should I tell my children to get into so that they can enjoy at least a middle-class existance?

Engineering, for starters (if your kids are willing to work for their undergraduate degree). As for "healthcare," if you mean medicine or dentistry, you are well behind the times. The Feds have already sunk their claws into those two fields so deeply that they're simply not worth the time, money, and effort.

I know several engineers who keep losing their jobs. Engineering stops to look like a long term career worthy of personal investment.

Are you in engineering? You do realize that most design work is now being done overseas. Wages for engineers are also very stagnant. Unless you are using engineering as a stepping stone to law or management, that isn't' a good choice.
