I heard on the radio yesterday that the embroidery for many wedding dresses is done in India. They make the dress here, or in China, ship it to India, and then it comes back to be sold to you for way more than it's worth.

That and that the economy is likely never going to be the same. Nobody is buying anything they don't absolutely need, companies are not hiring because nobody is buying (included governments). Everybody is clinging to what assets they have, fearful for the future. Me too!
