“All of my adult career has been spent around one central question — what’s happening to working families in America? Why has America’s middle class been hollowed out?” she asked the crowd. “The answer is not that people don’t work hard.”

The senator mentioned money as a corrupting on public policy, pointing to prescription drug costs, student loan debt and unfettered drilling for oil among the examples. Warren said the government as it currently operates works for those moneyed interests.

“It’s on the side of big drug companies, not people who are trying to fill a prescription. It’s on the side of big financial institutions, not people’s whose social security number was stolen,” she said in the interview. “When government is on the side of giant corporations and not the people, day by day, inch by inch it gets harder for working families to have security.”

Warren told the crowd, “We have to remember in this room, there’s a whole lot more of us than there is of them.”
