Boss I laud your efforts and intentions, but look what's going on at present (in Ja). Scholarships are being offered to many young people for school in the US. I'm talking about STEM majors. Will they return to Ja after living a certain life? (especially if they are educated on the East coast). I doubt it. Ja is in serious trouble for the long run.
I have to agree ; prostitution won't move Ja's economy (same can be said of gambling et al). It's as if the island is bankrupt of ideas. Criminal activities (forging, stealing , lying, murder et al) are on the rise though.
