I thought this was the most interesting question also.

My own experience bias suggests there is a scale problem related to skilled workers. That is to say there are fewer people with skills needed to achieve the work demanded (by the whole system).

There could be a number of factors here but I’d have to assert education and incentives have not kept pace with the demand. I think this holds true even if we say the projects are more complex than ever or if the technology has advanced rapidly. It still seems like an imbalance of skilled workers to the work.
