But, the one million in this scenario will be reached in 2029...On what do you plan on living till then?
The most important thing of all, who still thinks that a million $ in 2029 will buy you the same things 1 million does now? Even with a 3% inflation rate, you're looking at 750k instead of a million, and remember that the printing machine is in full swing, it takes just 6% to halve your future earnings.
Decent and 3rd world country? That doesn't make a lot of sense, if a country is "decent" is by no means 3rd world. And I would have healthcare the last thing on my mind, the first is the bureaucracy that might end taking half of my money and crime that might take the rest. Probably the safest pic would be the Baltic countries or the Visegrad group, 1 million (now!) would suffice for a noncapital city, but only if you're in the 50 already. One million will not help you live too comfortably if you start at 40!
The trick is to continue having income while waiting for the $1m price.
Well, but I guess that really isn't technically "retiring"..
But really though, living in a 3rd world country can be decent unless you literally live in a country like Venezuela. There are really decent 3rd world countries out there! They're mostly only crappy when you're in poverty; but if you have the money? It can suffice if you like living modestly.
But yea, just an opinion. Definitely not for everyone.
