Not to get too soap boxy, but that's exactly how the upperclasses have used divide and conquer to hold onto disproportional political power. It seems "wrong" to you, but imagine we went back to the tax rates set in the Revenue Act of 1942 with brackets adjusted for inflation: a family with a single tech exec or engineer making 6 or 7 figures a year can live well within their means and still have to drastically cut back on their quality of life under those tax rates. Someone with a hundred million dollars of productive assets probably wouldn't notice a change in QoL at all, unless they measure it by yacht-foot or jet-seat.
Almost all of us are N paychecks away from bankruptcy. The only difference between us is what number N is.
There are people who do nothing and dividends from their assets pay for their lifestyle and grow their net worth forever without labor. Those are the few actual upper (economic) class people!
The way I see it: the underclass has to work hard to move upwards, the middle class has to work hard to stay where they are, and the upper class has to work hard to move downwards.
