so, has anyone actually seen anything official about raising the age to 70?
Yes, in several countries, among them are...
Honduras
Bolivia
Argentina
Male
Benin
Syria
Jordan
Mauritania
And, several others.
Not done yet, only under consideration.
If it comes to pass, it will allow the younger set (such as they are) to work in their choosen profession, should they chose to do so.
Junior guys that don't especially like this arrangement, will just have to lump it.
Tough sh!te.
Edited to add...
It is quite likely that the 'change' will come from the EU, first.
