Well, if recent history is a guide one banker's wealth is another man's loss in a foreclosure, short sale, or tax to be paid for bailouts
Now if people start acting as rationally as the businesses and start strategic defaults en masse this can change a bit, but it's unlikely to happen.

Banking's important too, though, without it most businesses would not have the capital to invest in whatever they need to invest, and without the convenience of things like commercial paper the administrative costs to most medium and big business (which is actually the one that makes most of the wealth and jobs) would be much higher and the whole economy will be a whole lot sluggish.

From everything I've seen I've concluded that it is pretty much the same thing no matter which profession. There is always a demand for the people who are really, really good at something. It doesn't much matter if it's machining, plumbing, business consulting, teaching, etc...

The only difference is that some professions are more local, so people in them are more sheltered from having to compete with their peers worldwide.
The other thing is that the manufacturing has got the largest increase in productivity over the last 50 or so years. It's not that it has shrunk, but that a lot of it has become automated and is much less labour intensive than it used to be.
It's pretty much analogous to the industrial revolution, the likelihood of manufacturing jobs getting back to their old levels is the same as the likelihood of crafts becoming the main means of production of goods.
Yes, you can still buy all your clothes and shoes bespoke and they will certainly be of higher quality than the mass produced made in china/india/thailand/etc. versions, but if you are middle class you cannot afford it.
I don't think there is a large percentage of SRP members who wear daily Allan Edmonds shoes and these are only about $300, made in USA. I bet most wear stuff that's made abroad, likely in asia, so it is a matter of our own choices as consumers too.
