“Wealth Inequality in America,” a six-minute video produced by a YouTube user named “Politizane,” casts an interesting angle on the plummeting savings rate. Set to depressing piano music and packed with crystal-clear animations, it gives a powerful snapshot of the American economic landscape. Noting that “The top 1 percent own nearly half the country’s stocks, bonds, and mutual funds,” the video goes on to contrast those impressive holdings with the rest of the country. By comparison, it points out, the bottom 50 percent of earners own only 0.5 percent of those investments.
