I didn’t believe either but the old saying “If it’s in the press it must be true” still stands. Many of those programmes are from 2002. On the basis of one programme many years ago I heard a serious comment re. Florida which stated that if 3 houses were purchased then permanent residence in the USA could be obtained. I thought that there was a new loophole and researched…of course, it was a deliberate lie. I am sure many must have fallen for it.
I believe that these programmes should carry a disclaimer at the beginning stating that they are for entertainment purposes only.
