Is that the correct way to think of society? If the ‘poor’ are materially better off than were the middle class 40 years ago, is it still a useful distinction?
The middle class in America in 1960 had a home that averaged 900 square feet. They had one car that wouldn’t even be considered safe to drive if made today, and which lacked most of the features found on today’s entry-level vehicles. They had a black and white TV maybe 14" in size, and were lucky if they had a washer and dryer. They didn’t have microwaves, self-cleaning ovens, dishwashers, etc. They had one telephone, and long distance was so expensive that people used it rarely and then watched the clock carefully when talking to someone. Their families were bigger, but they typically only had one bathroom. Etc.
Today, the average ‘poor’ person in America has a cell phone, a computer, a big screen TV, air conditioning, washer/dryer, dishwasher, microwave, a car (sometimes two), and many other amenities either not available to even the middle class of 1960 or very expensive. And I’m not talking just about technology - I’m talking about real purchasing power. For example, access to fresh fruits and vegetables is better for the ‘poor’ today than it was for many members of the middle class in the 1960’s.
The ‘middle class’ is not a hard and fast description of quality of life. It’s a political construct. It means different things to different people, and it’s always changing depending on the goals of the political class and political activists.
If we were to define middle class in terms of access to basic amenities and luxuries, then the middle class today would be much bigger than it was even 20 years ago.
If we define it in terms of purchasing power, then it’s still bigger than it was in the past - in constant dollars, the median household income was $40,000 in 1965, and it’s $50,000 today. That doesn’t even take into account the increased purchasing power due to the improvement in quality of goods. That’s just raw income corrected for inflation.
It’s only when you start defining it in terms of current income compared to other classes that you can find a case for it getting smaller. But even then, there are all kinds of nuances that change the conclusion. For example, shouldn’t you consider benefits, vacation time, and retirement age?
How about leisure time? Access to automated appliances means housework is a fraction of what it used to be, and really shrinks one of the big distinctions between the middle class and the wealthy class - access to servants. Today we all have servants. This one factor alone really shrinks the real-world differences between the rich and poor - in the past, the poor and middle classes spent a huge amount of time on menial labor around the house that the rich didn’t have to endure. That gap is much smaller now.
Should you look at pre-tax or after-tax income? Taxes on the lower middle class and the poor have been declining for a long time.
The middle class is often determined based on Education, job type and income compared to other classes. For example, The lower middle class is often defined as being comprised of semi-skilled laborers with slightly below median income - for example, craftsmen or technicians with 2-year diplomas. The upper middle class would be educated working professionals - engineers, job foremen, chemists, lawyers, etc. They would have above-average incomes. “The poor” are often determined to be people with low educations working in non-professional occupations and requiring government transfer payments to maintain their modest standard of living.
It’s these kinds of categories that are breaking down. You can now find bus drivers making $100,000 per year, and lawyers making $35,000 per year. Government transfer payments have moved up well into the middle classes. There may be more job stability for a Wal-Mart worker than for a computer programmer. More and more professionals are working on contract, meaning they have no employer-provided retirement benefits, while a public sector blue collar worker may have a retirement plan that a private sector professional could only dream about.
So when people say the middle class is shrinking, you have to ask them to define the terms before you can even tell whether their claim is true. And then you have to ask whether the distinction even matters in today’s world. It might be better to drop the labels and just talk about the real problems people face rather than defining everything in terms of class.
