However, my point upthread was not related to this alleged income inequality but rather the basic standards of living that almost all of us in the rich West enjoy today compared to even just 50 years ago. The middle class today is absolutely better off than the middle class of 1970. We may be less content than our counterparts were back then, but that's not because of the underlying economics of it.
It is true that there are barriers to prosperity that are faced by the lower classes and we should always be looking for ways to remove them.
I think if you judge standard of living by a level of comfort, or possessions, then people in all classes today are likely better off than they were 50 years ago.
I think there's more to overall quality of life than just maintaining a "standard of living" though. We're also talking about the ability to chart one's own life and improve that standard of living. That's the thing that I think is getting progressively harder. At least in my personal experience. I'll use my family as an example to show where I'm coming from:
My grandfather was a middle manager at GM in the 60s. It was a good job, but not amazing. With nothing but a high school diploma was able to comfortably support a family of 7(!) on his income alone. They had a nice home in a nice neighborhood with doctors, lawyers, etc as neighbors. All 5 kids had their college educations paid for (mostly small, expensive liberal arts schools). He got divorced
twice and still had enough to retire to FL and fish on his boat every day. No way that scenario is possible today on a middle manager's salary.
My wife's grandfather was also the sole bread winner for a family of 7(!) with nothing but a high school diploma. He was a truck driver. They had a more modest home in a more modest neighborhood than my grandparents, and the kids didn't go to college but they spent their weekends at one of their 2 lake houses (!) fishing and waterskiing behind one of their multiple boats (!). He retired comfortably with a nice pension. 3 homes, multiple boats, for a family of 7 on a single truck driver's salary? It wasn't glamorous back then, but I don't see that really even being feasible today.
If we look at the next generation (my parents and inlaws), only 1 of the 4 parents had a college education. No high earners in the bunch, but with 2 incomes they were able to carve out enough of a living to own typical homes, raise small families (2 kids each), get new vehicles every few years and have enough left over to play with race cars, boats, etc on the weekends. They're now mid-60s and still working. Retirement will be heavily dependent on social security with a mix of self funding. I think people working 2 basic factory jobs, or as a mechanic and teacher today would struggle to provide the same things in the same situation.
That brings us to my wife and I. Both have healthy incomes (not exactly impressive compared to many here, but we do alright in the scheme of things). We're both college educated (state schools). We both worked full time while in school to avoid tons of student loan debt. We have a single child. I think we're doing better than either of our sets of parents, but it's required a lot more sacrifice to make that happen, and we started out with advantages of being white, and coming from stable, blue collar, lower middle class types of homes growing up.
The general trend for the last 60-70 years seems to me that each generation has had to work a bit harder and/or sacrifice a bit more than the prior one did in order to live a comfortable life. 1) dual income 2) college education 3)smaller family (started later in life) 4) fewer toys etc. This was clear to me pretty early on, and has impacted my choices profoundly. I'm not trying to play the victim here at all. I don't want to take other people's money, and it's not lost on me just how bountiful my blessings are. But this view has been a driver for me to make the choices I've made, sacrifice how I have, and pursue the MMM way so that it's easier for me to have that stability as well as increase the chances that my kid will have similar or better opportunities. I'm comfortable with the argument that this view is incorrect. If I'm right, then we'll be in position to help my kid's chances of success. If I'm wrong and things aren't getting progressively more difficult for each generation, then we all end up with more money that can be shared with people we care about to make their lives better. I don't see a downside to either outcome.
