There are war-torn countries, people full of poverty, who still voted, 60, 70 percent. If here in the United States of America, we voted at 60 percent, 70 percent, it would transform our politics.

Inequality also distorts our democracy. It gives an outsized voice to the few who can afford high-priced lobbyists and unlimited campaign contributions, and runs the risk of selling out our democracy to the highest bidder. And it leaves everyone else rightly suspicious that the system in Washington is rigged against them - that our elected representatives aren't looking out for the interests of most Americans.
