Reading some of those letters made me realise how different risks families have and take in the US and the EU.
Assuming the state pension system will still be running by then and won't be totally broken due to birth rates < 2.
At least in countries such as Germany they are currently facing issues because of the low amount of young payers in the next few decades. And politicians are just ignoring this to get votes from the mostly elderly population (recently in Germany: pension raise of >5% while inflation is at almost 0%).
Sorry, but I think depending on the pensions in the EU is waay to risky. It'll probably fail like a ponzi scheme in few decades. I guess US-citizens are actually better off, because they have more money to save on their own.
