of course, in some countries the 'reverse Mortgages" do the trick to keep the elders afloat.
Thats another way to provide retirement income for a vacation home.
Drains the proverbial tank somewhat, but to some, it may not matter.
If you have spent all of your savings educating your children to the point where they are self-sufficient professionals... go ahead and "live it up" in the golden years.
My 2 cents
Life expectancy is increaing all the time for those that have reached 65 or 70. Extensive help may be required in later years. Assisted living is expensive in the US and advanced countries. A property in a developing country makes a nice nest egg should independent living be difficult or long term medical care be necessary.
