It is very unfair for British pensioners. But what will British pensioners who have a frozen pension do if there is a world war, which is quite possible this decade, because it would cause hyperinflation? 221 pounds x 52 weeks = 508,156 Baht. In hyperinflation, this will drop massively. They will have to use more and more of their savings each year to meet Immigration's requirement of 800,000 Baht. If they can't, they'll have to retire in the UK, which will be very tough.
