You may know they tried to get a retirement bill through in the late 1990s, Sheena, though the guy who introduced it is no longer in Senate. It failed because it only got the support of the senators whose regions would benefit, Florida, New Mexico and Arizona eg and there are far more cold northern states that wouldnt really benefit. Anyway it never made it. I think if everyone who wants to retire to Florida emailed and you got someone to introduce it again based on support in Florida, the same thing would happen again. There is a lot of self interest in American politics! Unfortunately.
