> Housing has become much more unaffordable.
That's hardly surprising though is it? The number of people in the US has almost doubled since 1960, and urban population density has increased much more than that. Any expecation that everyone will be able to afford a detached house in any proximity to a metropolis is clearly unreasonable.
> Higher education has become much more unaffordable.
Again, the admissions rate hasn't really kept up with the population has it? Also there's a labour shortage in lots of skilled trades, construction and agricultural labour; and a labour surplus in finance and law. Do you think it's reasonable that everyone expects to attend higher education?
> Retirement income has become much less guaranteed.
I'm not sure how you'd measure retirement income "guaranteedness". Also see "Pension Timebomb" for how actually guaranteed those pensions are.
> Employment is much less stable than it used to be
Do you have a source for this? Ideally one that controls for people changing employment to advance their careers? This is much more common these days for the reasons outlined in the article.
Yes, after being evicted from a place you cannot afford, or after any other trying circumstance, telling people to focus on what they can be grateful for instead of what to be angry about is exactly the right thing to do. What business is it of yours or anyone elses how much money someone else has? Who cares if they have more or less than last year? How is that related to you personally being unable to affort rent due to being unemployed during a pandemic?
