"upper class" never meant a relative income percentage. It has always meant a lifestyle. "Upper middle class " means you can afford a three or four bedroom house in a safe location with good schools, that you can absorb a series of financial shocks like dead appliances and car accidents without trouble, that your whole family has decent health insurance, that you can choose to go on vacation every year to a foreign country and still save for retirement. And so on. Wealth capture to the very rich has made us all poorer.
