At that point the older generations will already be wielding their political power with an iron fist to get the last drops of all the money and resources that do not get replenished. This was never an apocalypse type issue, but always purely political and the younger generations will suffer for it. THAT is the main issue, if you are old enough now you'll be fine, you'll get to "eat" the last little bit of stuff and then you pass away. It's the folks that have 60 years to go that are in trouble. Convincing the elderly to not vote or to take "their" stuff away is always going to be unpopular when 60% of the voting block in that age.
