Re: So...
@Qwelak.
Not sure you understand how the state pension works.
When it was setup, the government of the day took contributions and said they'd give the people something back. Interestingly, the contract keeps changing as the 'get something back' keeps changing.
Did they invest the money wisely to grow and become a pot to pay your pension later on? No, they did not. They spent the money immediately. They surmised that the contributions of workers when you're retired would be used to pay your pension. Similarly, when those workers retired, the workers at that time would pay their pensions. On and on to infinity.
So, the government got an effective income which gradually declined as people started claiming the pension. Then, it was self-sufficient. Current workers pay for retired workers pensions. Job done. Big pile of cash up front to fund things. Now, this was partly to pay for reconstruction work (and other things) after WWII.
However, as people live longer, the terms of the original pensions are looking rather generous. Workers can no longer fund the pensions of currently retired people due to the age they're living to etc.etc. Also, ratio of workers to pensioners etc. Hence, the pensions crisis we're (in a very poor way) trying to deal with at the moment. However, it did give them a big pool of money to start rebuilding after the war!!
So, no future workers, at least your state pension will be gone. Money purchase pots may be OK. Defined benefits schemes could also have problems if the number of workers declines a lot.
So, significant proportions of your pension are quite heavily (or totally) dependent on future workers and hence children being born and growing up. This will be true for many, many decades yet.
