New research finds Pb is the hidden villain behind violent crime, lower IQs, and even the ADHD epidemic. And fixing the problem is a lot cheaper than doing nothing.
The first is this: Income inequality has grown dramatically1 since the mid-’70s—far more in the US2 than in most advanced countries—and the gap is only partly related to college grads outperforming high-school grads. Rather, the bulk of our growing inequality has been a product of skyrocketing incomes among the richest 1 percent and—even more dramatically—among the top 0.1 percent. It has, in other words, been CEOs and Wall Street traders at the very tippy-top who are hoovering up vast sums of money from everyone, even those who by ordinary standards are pretty well off.
Second, American politicians don’t care much about voters with moderate incomes. Princeton political scientist Larry Bartels studied3 the voting behavior of US senators in the early ’90s and discovered that they respond far more to the desires of high-income groups than to anyone else. By itself, that’s not a surprise. He also found that Republicans don’t respond at all to the desires of voters with modest incomes. Maybe that’s not a surprise, either. But this should be: Bartels found that Democratic senators don’t respond to the desires of these voters, either. At all.
