According to the latest unemployment numbers, the U.S. unemployment is at a low rate of 4.1% and many companies are having a hard time finding workers. This good news for job seekers may have some scary implications for people needing help with care in the future. Much of the labor shortage is for highly skilled workers in fields such as technology and advanced manufacturing. However, the labor shortage also affects so-called "lower skilled" work such as trucking and retail. In fact, many people are worried that this is a long-term trend that could impact future growth opportunities in this country.
