>I've learned that strong political beliefs in either direction limit your ability to make rational decisions more than almost anything else. Strong political beliefs in any direction, not either direction. This complaint also relies on the fictional 'rational decision about a political issue' vs. 'political decision' distinction, where your opponent is always "playing politics", but you're always simply being empiri…
Not in the median it isn't.
Your claim is that median wealth has in some meaningful sense decreased in the United States during my lifetime of just more than half a century. Because of various family circumstances and my own career choices, I have generally been below the United States median in income much of my working life, and have always been below the United States median in financial assets or possession of land and real property. And yet I have every reason to believe the author's claim that "The country is richer than it's ever been," and not just for the fat cats, but for me too.
For one thing, we have this newfangled Internet technology that allows you and me to have a thoughtful discussion while shattering barriers of distance. Having once lived overseas when my only affordable means of communication with my homeland was postal aerograms, I count this as a HUGE increase in wealth, which is certainly enjoyed by most at-or-just-below median people in most developed countries. (I communicate with friends and relatives from a variety of countries online every day.)
So I call baloney on your assertion. But perhaps you have evidence that will convince to change my opinion. Discussing this issue thoughtfully will also make both of us richer than we used to be, so I am all ears.
AFTER EDIT: You do make a good point that political opinions can (and do) differ along more than one dimension. There are many, many different kinds of political opinions, including many that are inconsistent with other opinions held by the same person.
