(USA TODAY) -- Brick-and-mortar retailers have been suffering from slow economic activity for years, as well as from increased competition from online retailers. The rise in store closings is a prominent sign of their struggles. Weakened companies cannot afford the real estate and personnel costs that go along with supporting hundreds of unprofitable locations. The clearest proof of the problem was RadioShack's recent decision to close more than 1,000 stores.
RadioShack is hardly alone. During that last several years Gap has closed 20% of its locations. Even Macy's, which has forecast strong earnings and is considered the most successful of the mid-market retailers, closed stores recently.
