On February 9th, President Obama is scheduled to present a spending plan to Congress in regards to his effort to help 30 million Americans put more toward retirement. This plan will include automatic enrollment into Individual Retirement Accounts, so employees are able to maintain savings even when switching jobs. In addition to this, employees at small companies will also be allowed to have a pooled 401(k) plan.
