The cycle works the other way too. I helped my dad remodel an entire three-story house, including digging foundations for an extension.

I'll be damned if I chip my nail polish on manual labor these days. Not because I'm "above it", but because I hate it with a passion. If I can pay somebody to do it for me, awesome. If they actually enjoy their work (and many contractors do), it's a win-win, as far as I can tell.
