And none of that is based on vehicle technology. Again, people used to save a lot of money doing their own car repairs. Today, that is nearly impossible for anyone who is not a highly skilled and constantly training technician. I know mechanics who have made a career out of car repair who can't keep up with all the tech anymore.
Sure it is, whether you want to admit it or not newer technology has made cars safer, more efficient, and more reliable than ever. You seem to "know" a lot of people or uncles or whatever that give you anecdotal impressions that don't bear out by any better reference than your fond memories.
You said it costs more to maintain a car today, but bottom line the only source I found it was clear it wasn't even close over twice as much to drive a car back in the day.
I also see that there must be some critical flaw in the methodology of your source, considering that they also include things like the cost of insurance and gasoline. Insurance wasn't even required in 1950, for example.
That would probably favor the 1950s car if their calculations at the time didn't include paying for insurance, but I'm sure you have another source right? Something better than AAA like maybe your giddy memories of your cousins driving cars that never needed repair and shot fairy dust out of the tail pipes?
All if this is irrelevant anyway, a red herring, to distract from the point that a typical car today still costs twice as much to buy, for whatever reason, making basic individual transportation impossible for a larger section of the working class, or otherwise costing them in other sectors of self-support which they must shortchange to fill the need.
Actually it seems most of your post is a red herring to distract from almost everything you claim isn't born out by data and is never backed up by any reference other than you. Per capita far more people own cars today than ever before, and far more people own homes, and fireplaes in those homes, and they spend money owning their cars every year, and they get far more house and car when they do buy them.
Go find a graph showing what percentage of income people spent on the essentials of food, clothing, housing, and healthcare 1950 versus today. The only one higher today is healthcare and combined they make up a much smaller percentage because now we spend more money on bullshit like the internet and computer you are using to wax nostalgic about the 1950 when every sat on gold thrones and smiled.
