The retirement insecurity is a consequence to lifetime expectancy having increased vastly beyond retirement age. The health care bills ? You couldn't even get them before, as all the healthcare one could expect was penicillin, aspirine, bandages and hot soup. Housing ? People would live with their parents until and even after they married. Now people can afford to move out and divorce.
Social behaviour and expectations have changed to fill in the opportunities offered by newfound wealth, driven by the search for longer life and higher social status.
For physical comfort and mass produced entertainment, yes, they have never been cheaper. But definitely not opportunities.
Quality education, the bedrock of opportunity, is more expensive than ever, even for the middle class, and the poor have long been largely priced out.
It doesn't matter if all the knowledge in the world is available online because you still need a quality education to absorb that. When the wealthy decide to pull their kids out of school and give them the internet as a substitute I'll reconsider that.
Safe communities are also something increasingly inaccessible to the poor.
The disparities in opportunity are especially pronounced in urban areas and rural and post industrial areas, but the trend is the same practically everywhere.
Not to discount the importance of the rest of what you've listed, but there are still immensely important things that are not available at lower income, or that are only available at higher income.
One tweak is having a robust estate/death tax. That will create a more level playing field. People will complain about double taxation because their whole lives they are building a fortune for their children, but passing tens of millions of dollars to your grandchildren is not something we need to protect.
Talk to the working class (uber drivers, janitors, &c) about their lives. They work very long hours to just barely scrape by. Housing and medical care are very expensive compared to wages.
Take a walk outside. Unbelievable numbers of people living in misery on the streets. There are entire tent cities sprouting up like mushrooms.
It's bad, in absolute terms.
I dont need a Car, nor a Smartphone nor any of the example they gave. I need Food, Water, and Clothes. Three most important things. Then I need Shelter. First three is solved, the latter happens to be the root of all evil.
Maybe that is what you mean by "social status", but an very unequal distribution of power is not a good thing in a society through many's eyes.
I think that is a profoundly naïve narrative.
That's a pretty big exception to what you're talking about.
Daycare is another.
The amount and the quality of goods and service that is available to even the lower income bracket has never been better; most families can afford access to a car, a washing machine, food from around the world, unlimited entertainment, unlimited knowledge, air travel, telephone, etc. etc.
Put another way, all the money in the world can't buy you a better phone than a 1000$ one, and that phone is only marginally better than a 100$ one, which everybody can afford. And that is how it works for most things nowadays.
The reason people are so pissed about inequality, is that despite people having material and service equality like never before, social status remain extremely unequal. But that is human nature, and no amount of money redistribution can change it.
