We've been conditioned to associate a persons wealth/happiness with their possessions. Having a RV "down by the river" isn't the American dream of home ownership. Some would even say that greed was good. I'm thinking that a person living in an RV FT is looked at much different then someone that owns a suite on a
cruise boat. I find the argument of jealousy a wishful thought of those that want to FT and not at all accurate of those with a more conventional lifestyle.
Not everyone likes to travel, many will even suffer from extreme anxiety prior to leaving on a trip. It is much more comforting for them to sit back in a secure and known environment and look at travelling through some digital media that someone else has created. Can you imagine the stress level that FT'ing would create for them.
I find those that do not travel (or very little) to have a very small view of the world. Scary to think that their only information is coming from Fox news, CNN, the weather channel, and some local group(s) (church, bar, a guild, etc...)
