Excuse me, I mispoke, I said Dumocrats (habit I'm afraid) and actually meant Congress in general.
His policies were unpopular. He attempted to stop or slow down speculation and the financing thereof by banks. His appeals to the Federal Reserve, Congress and Governor Roosevelt (to propose stiffer regulation of the New York stock exchange) went unheeded.
He also opposed farm support measures and felt that no government agency should be involved in the buying and selling and price-fixing of any products as this would lead to greater overproductionand apply downward pressure on prices. He preferred private means of control.
As to the good guy thing, AReaganGirl, your right, he never took any government money for his service, giving all of it to charity.
The state didn't regulate the stock exchange, the federal government did.
