The baby boomers are going to be the richest retirees in our nation's history. So what are they going to do with their cash? Spend it, of course. With plenty of time and a penchant for enjoying life, the baby boomers are expected to drive the arts and entertainment sector, which is projected to increase in employment by 31.3% over the next decade.

The arts, entertainment and recreation sector, which includes anything from golf courses to casinos, will also benefit from a younger clientele. Over the last decade, the saving rate among Americans has fallen, partly because of an increase in the cost of living, but also because of increase spending on discretionary items. This trend, coupled with the demand from baby boomers, provides entrepreneurs with many business opportunities.
