By the way, Tucker's latest guest (Dave Collumn) touches on this subject to some degree. While he's not talking about replacement automotive parts, he goes into detail about what a collapsing empire looks like.
His prediction (and I agree with this based on what I've witnessed around me in the past decade or so) is that we'll witness society fall apart from the middle. It will become harder-and-harder to find competent workers or people who are very skilled at a particular trade. More-and-more you'll have to know how to do everything yourself.
I concur with this. Just finding a mechanic that knows what he's doing is hard enough as it is. Try hiring employees that will show up when they're supposed to, know what they're doing, etc. We know the manager at the local Dairy Queen and he is constantly lamenting about how it's impossible to find good workers. He said they're almost all teens and they have to be supervised by an adult at all time or they'll burn the place down unknowingly. They regularly do not show up to work for days on end (they don't call in either), then out of nowhere they come in to work acting with excuses such as, "sorry, I just didn't feel like coming into work".
All around us you can see it happening. WIth the birth rate at an ever increasing decline, more men simply "tuned out" from the work force, and millions of low-skill, welfare state illegal immigrants, the future doesn't look very bright. This is of course happening all throughout the western world and if I had to guess it's only going to get worse.
It's hard to find quality anything these days. That's unfortunate because I'm one of the people who is always willing to pay more for a high quality part that would last me decades.
