Contrary to your claim that the Federal Reserve collects 6% on the total M1 money supply, that's 6% paid out on the capital stock that the member banks put into the Federal Reserve banks.
The paid in capital from member banks for all of the Federal Reserve banks totals $27 billion ($27,217,000,000). The paid in capital is the capital that banks put up to form the Federal Reserve banks. And the Federal Reserve banks pays a profit of 6% on that or $1.6 billion in annual interest.

So understand that, the total of all member banks of all Federal Reserve banks got $1.6 billion in interest on their paid in capital. And the Federal treasury got the rest of the profit which was $88.9 billion in interest. Federal Reserve Profit

Forget Cyprus, Nobody Is Stealing from Depositors More than Bernanke
By Bernice Napach | Daily Ticker –
“At this stage of a recovery normalized interest rates should be around 2-3%,” says Rickards. “Apply that 2-3%…to the entire multi-trillion-dollar deposit base of the United States of America and that’s a $400-billion per year wealth transfer from savers to bankers so they can pay themselves bigger bonuses or make crazy bets.” Over time, Rickards says, that wealth transfer could reach $1 trillion.
Rickards says zero interest rates are just one way the Fed is fleecing depositors. Others include increasing inflation, which Bernanke is trying to do, and taxing deposits like Cyprus is pushing for. “Bernanke is stealing more money from depositors than Cyprus is... looting everyday Americans—teachers, firemen and retirees,” says Rickards.
