You've totally ignored that fact the automotive sector, this working middle class are the ones that send their kids to college and buy them iPhones for x-mas.
That's right. That's because it's no longer true, because the automotive sector no longer comes close to having that kind of employment.
Today, the working middle class that send their kids to college work in the service sector, selling clothes at Wal-mart, selling insurance, or designing iPhones.

Perhaps a little thought experiment will make it clear. Let's say that I invent a process that can, literally, create cars out of thin air. Using nano-technology and controlled fusion, I can literally take oxygen, carbon dioxide, and nitrogen, fuse them to make the substances I need, and produce a car at the touch of a button.
How many jobs will I create by the invention of this tech? None in manufacturing. In fact, I'll probably destroy a number of jobs, because I can by myself produce as many cars as the entire state of Michigan did at its heyday. I'll completely undercut the manufacturing base of this country, or probably the entire car-manufacturing world.
But I'll also create thousands of jobs in sales, because these cars can now be sold for the cost of transport, and I can make and sell them cheaply enough that any family can treat them as entirely disposable. If it's a nice day and you want a convertible to take down to the beach, just grab one. When you're done, drop it off at a recycling place and melt it down; I'll make more.
I can easily create more jobs in sales than I destroyed in manufacturing, because I can now supply cars (and people can want cars) on an entirely new level. I can literally, all by myself, make more cars than people can sell.
I can also easily create more jobs in
transportation than I destroyed in manufacturing, because all of these cars are being created in my factory in Hayes, KS, but need to be delivered to customers all over the place. Since I'm delivering so many more cars than before, we need much more transport capacity than before, which means more people working in transport. I can make more cars than people can deliver.
Sure, this is an exaggeration. But it shows the central point. As the costs and efficiency of manufacturing improve, the employment prospects (and the money to be made) in manufacturing get less and less. It's not an exaggeration to say that one person in a car factory today is as effective as a hundred people were in 1950 -- which means that if one person in four was employed by the auto industry in 1950, you only need one person in 400 to be working there today to maintain the same level of industrial productivity.
Which means that everyone else is free to do whatever else they like. In most cases, they will be taking service jobs. Instead of
making cars, they will be fixing them. Or selling them. Or transporting them. Or fixing, selling, transporting, or designing something else.
That's why the world's largest employer -- and the US's, for that matter -- isn't in manufacturing. It isn't even close. The largest employer is Wal*Mart, because it takes more people to sell clothing than it does to make them now. The second largest is McDonald's -- again, this is a service industry. The next is UPS, which of course, is simply transporting things around. We don't get to
actual manufacturing industries until GM at #7.
The "working middle class" that pays college tuition and buys iPhones doesn't need to work in factories any more, because the factories are sufficiently automated that they can churn out more than enough goods to meet our needs. But what they can't churn out are the services to meet our needs, services like stocking shelves, delivering packages, managing delivery schedules, planning advertisement campaigns, and designing new products.
Which is why the working middle class in the USA delivers services, not manufactured goods. Which is another way of saying that the USA is a service economy, not a manufacturing one.
Of course, they deliver services outside of the country, too. Most of our exports are also services. Apple doesn't just sell iPhones (and UIUC doesn't just accept students) inside the United States. And all the Chinese-manufactured goods that are on Wal*Mart's shelves had to get there somehow, usually on a US-flagged ship run by a US-based transport company. (There's a reason that UPS is such a large company.) When China sells a T-shirt to France, there's usually a cut of that sale that ends up in the States. Because the USA is a service-based economy (and has been for decades) and transport is one of the services it offers.
