The stock market is closed. Schools are closed. Government offices are closed. So what happened to everything else. The holiday, according to Wikipedia, "began in 1882 to create a day off for the working man. It is still celebrated mainly as a day of rest and marks the symbolic end of summer for many. It is a federal holiday." But look around. Everything seems to be open for business and there are a heck of a lot of people working. Only in the US do Americans celebrate a holiday by working. No wonder the rest of the world thinks we a bunch of idiots.
