Sen. Kamala Harris wants companies to prove they pay men and women equally. "Penalties if they don't!" she shouts. But there are lots of reasons, other than sexism, why companies pay some men more than women.

Harris also wants government to "hold social media platforms accountable for the hate infiltrating their platforms." But "holding them accountable" means censorship. If politicians get to censor media, they'll censor anyone who criticizes them.

Sen. Bernie Sanders wants the post office to offer banking services. The post office? It already loses billions of dollars despite its monopoly on delivering mail. Sanders also wants to increase our national debt by forgiving $1.6 trillion in student loan debt.

He wants to ban for-profit charter schools and freeze funding for nonprofit charters. That's great news for some government-school bureaucrats and teachers unions that don't want to compete but bad news for kids who flourish in charters when government schools fail.

Sen. Cory Booker once sounded better about charters, saying, "When people tell me they're against school choice ... or charter schools, I say, 'As soon as you're willing to send your kid to a failing school in my city ... then I'll be with you.'"
