Great countries don't break their major promises

"American workers have put money into the system for their whole working lives and are depending on it to be there for them when they need it," Steyer said. "Great countries don't break their major promises to their citizens.

"Under all circumstances, my administration will live up to the promise to protect Social Security, including by raising the income cap." More details on Steyer's plan, including how much he would raise the income cap subject to Social Security payroll taxes, were not available.
