Massachusetts had a tax-free holiday this month and I thought I would try to take advantage of it. Who doesn’t love an excuse to go shopping? But after only an hour of searching through retail chain stores, I started feeling bored and frustrated. The stores seemed to be carrying less merchandise than in the past, and the “look” had become homogenized. But the saddest thing of all to me was the overwhelming percentage of items that were made in China, even if the materials and designs were from elsewhere.
