Elizabeth Warren, American politician, senior United States Senator from Massachusetts since 2013. Professor, Harvard Law School.

There is nobody in this country who got rich on their own. Nobody. … You moved your goods to market on the roads the rest of us paid for; you hired workers the rest of us paid to educate; you were safe in your factory because of police forces and fire forces that the rest of us paid for. You didn’t have to worry that marauding bands would come and seize everything at your factory, and hire someone to protect against this, because of the work the rest of us did. Now look, you built a factory and it turned into something terrific, or a great idea. God bless. Keep a big hunk of it. But part of the underlying social contract is, you take a hunk of that and pay forward for the next kid who comes along.
