It is true. It is why old folk admonish young folk for fretting over problems that are measurably lesser than those they experienced. An automobile is a "a safe, efficient, comfortable, and relatively affordable machine that enables you to get to your climate controlled, 9-to-5 workplace without breaking a sweat". But it is also the only way that I can get to work, and it costs me significant amounts of money. A car is not all upside. It is a measure of both, and the balance differs among people. When I was an undergrad, if my car broke, I accumulated debt. I could not get to school or work without one, and I could not afford one that wouldn't break. It wasn't a clear source of well-being. On its face these lesser problems might seem ridiculous, but they aren't easily dispelled. We are not wholly rational beings.Therefore, the evil consequence of the poor getting richer and the rich getting richer at a different rate is that some people's feelings might get hurt.
