Target (and all discount retailers for that matter) doesn't really care about the experienced worker. It's a nice bonus but it is not part of their strategy. If it were, they definitely would of invested more into payroll, employee training, retention, etc. Of course, this just increases their costs, which almost always leads to higher prices (something you can't have when you are trying to compete with Wal-Mart.)
Speaking of the Wal-Mart, they've already proven that providing practically every product at rock bottom prices and not much else is resoundingly successful, so much so that everyone else has to play copy-cat in order to survive. The few 'loyals' that a retailer loses pales in comparison to the potential profit they could gain by following Wal-Mart's model.
Unfortunately, because of the lack of funding for employee investment, new employees are introduced in an environment where you are supposed to sell or do something but aren't really shown how to do it successfully. It gives the appearance that the employer doesn't care. Thus, the employee starts to not care.
