Whether that is a high or low threshold is of course debatable as all else ;-). However, to obtain passive income of 80k USD you'd probably need about 3 million USD of invested assets at around 3% mean dividend/interest so still a considerable sum of money. Of course it all is relative - and I assume you are much much wealthier than that as you are bringing this up - but from the Thai government point of view this certainly makes sense: those retirees spend their money in Thailand, pay sales taxes etc. No real downside as we oldies usually behave, don't drive like madmen... So I believe this scheme will remain in place and benefit Thais and foreigners alike hopefully for many more years to come.
