Take on Bad Actors and Bring Down Costs
As Attorney General of California, Kamala Harris took on the big banks to deliver for homeowners, stood up for veterans and students being scammed by for-profit colleges, and fought for workers and seniors who were defrauded.
As President, she will direct her Administration to crack down on anti-competitive practices that let big corporations jack up prices and undermine the competition that allows all businesses to thrive while keeping prices low for consumers. And she will go after bad actors who exploit an emergency to rip off consumers by calling for the first-ever federal ban on corporate price gouging on food and groceries, which will build on the anti-price gouging statutes already in place in 37 states.
Just as she did as Vice President, she will take on Big Pharma to lower drug prices and cap insulin costs, not just for seniors but for all Americans. And she’ll keep fighting to bring down prescription drug costs by taking on pharmacy middlemen, who raise consumers’ prices for their own gain and squeeze independent pharmacies’ profits.
