The state of retirement savings in America is in big trouble. According to Fidelity Investments, the average 401(k) balance among its 11.8 million accounts increased to $74,600 at the end of the first quarter 2012, a 62 percent increase since the end of the first quarter 2009. While it’s good news that balances are up, the number of accounts is alarmingly low for such an industry giant.
