Its a competitive world
The decline of the middle class in terms of inflation-adjusted earnings has a lot to do with the fact that we live in a competitive world and there are a lot of things in play. Manufacturing and marking is globalized. Labor and manufacturing costs in many countries is less than in the USA and manufacturing efficiency in the US hasn't necessarily been keeping pace with the competition and this is evident in boat manufacturing.
About five or six years ago I went to a European boat show near Vienna, Austria, and at the Bavaria booth they had a continuous video running. Not too many people were looking at it but I sure did. What was impressive was that they were going from design, using CAD, to production and assembly, using LOTS of robotics.
Just for the fun of it, I did a quick search to see if I could find a link to a video but came across their web page which shows some of the process:

All the fiberglass mat is cut by robots. Ditto the cabinetry. The web page shows robotic arms cutting out holes for the ports in the hull. Carbon fiber or Kevlar in the hull? Bavaria had that way back then.
And Bavaria Yachts isn't alone doing this. Sure, Catalina and Hunter do this too, at least to some extent, but the Bavaria video, even back then, was really impressive.
Why did Saber cut back or stop producing sailboats? Bang for the buck its hard to compete against the major manufacturers now and Saber didn't keep up.
The world population has been increasing at an exponential rate. With more people "looking for a job" in an increasingly crowded world, the value of labor will decline. American workers who compete on a world-wide basis have to compete against all those billions of people who are willing to do the same work for much less, so guess who gets the job?
Local Seattle/Everett news:
Boeing is looking to relocate their assembly lines to somewhere with friendlier and cheaper labor. Many local machinists want to have a march this Wednesday to show the union leadership that they want to vote again on the contract they just got through voting down. But why would they want to do that?
Boeing has put out a RFP to any interested areas who would like to have an aircraft manufacturing facility in their area. Since there has been so many states interested in having Boeing relocate to their area it seems a number of Machinists are having second thoughts. This is getting interesting. Nothing like a little competition.
