Similar to smaller and affluent towns on Cape Cod.I have two good friends who have both left the island with their family's due to the lack of affordable housing....not going to get any better anytime soon...
After Irma we rented a villa in Anse de Cayes. The houses on each side were filled with workers. Many vehicles, however they never interfered with our parking spot. Both houses on each side of the villa were occupied by workers. They never were noisey and were extremely polite. At the end of the week I brought a case of beer to each of the houses.Those seasonal workers often, as you say, stay in houses and apartments rented by their employers. Those places are thus unavailable to those born on St Barth, which was part of the original question. After Irma, many of those houses and apartments continued to be rented by the employers, even while their establishments were closed for repair and upgrade.
