It is a great benefit to the social cohesion of a society for there to be a strong middle class. It is almost a pre-requisite
Middle class is either an invented term or a term that means something different to everyone. I strongly disagree with your assertion that unions maintain a strong middle class. Unions give benefits to their members at the expense of the rest of America.
How many hours did a typical, non-supervisory American have to work in the past to furnish his home with Sears‘ lowest-priced versions of each of these items: automatic clothes washer and dryer, full-size refrigerator-freezer, 30-inch electric range-oven combo, television, electric vacuum cleaner, automatic toaster, 10-cup electric coffee maker and 20-gallon electric water heater?
An ordinary American worker in 1956 had to toil for 456 hours — nearly three months — to buy all of these commonplace household items from Sears.
By 1975, an ordinary worker had to spend much less time — only 252 hours, just over a month and a half — than did his 1956 counterpart to buy the same items from Sears.
But what about today? Is it true that economic gains for America‘s middle class have stopped since Gerald Ford occupied the Oval Office?
Here‘s evidence that those gains have not stopped: An ordinary American worker today, to buy the same bundle of items from Sears.com , needs to work a mere 105 hours — just about two and a half weeks. That‘s nearly a month less work time than was required in 1975, nearly nine weeks less than was required in 1956.
