You are correct, Mike. If the government gets involved the ensuing regulations and taxes will only serve to return cruising to what it once was - a vacation that few middle class people can afford to do on a routine basis, if at all. As with all corporate taxes, the corporation doesn't pay them, their consumers do. So there goes the $199 4-night cruise.
It isn't lost on me that I am typing this on an iMac computer built in China by cheap labor, because if it were built in the U.S. few people could afford to buy them.
We have already seen many cruise line assets being moved to Asian markets because of demand. That would no doubt just gather more steam should the lines be taxed and regulated out of U.S. ports.
