Why is the U.S. behind the curve?

Everywhere I look online I see workplace massage thriving in the UK. In Australia it's been going on for decades. I have friends in Canada that say it's a normal part of the workday there. A lot of articles and research done on workplace massage have been conducted in other countries. Why are we as a country and a culture so slow to adopt new ideas, even when they've been proven effective by other nations?

Granted, we are starting to come around. If you look at my blog post a few back I have a list of a lot of companies in the US who provide massage for their employees and are enjoying the benefits of increased productivity, decreased turnover, and decreased health care costs. It's just interesting that we like to stick to what we think works in the traditional sense, and take very little notice of what other cultures are doing, even when it is proving to be effective.
