I think you are completely ignoring the single most important factor here, ge reason why more older people are in power.
The demographics in the West are heavily skewed towards older generations who had a lot more kids than their kids, who are now having less kids than their parents. The power discrepancy directly follows from that and in my opinion so does the disconnect between the generations.
The "retiree draft" is just an absurd proposal which will do exactly one thing: increase resentment and further disconnect.
It's not just demographics.
People tend to make social abd economic connections over time, and to be actual mover and shaker you do need key supporters.
That's where democracy also fails. The shorter you're around, the lower chance people heard about what you've done and who you are, no matter how good or bad you are at something.
(Same applies to functionaries often enough.)
But young people, who are more ambitious and less established are also more willing to take a chance on young and ambitious people. I don't see how this is unconnected to demographics.
Demographics play a part still having 70% of our government officials over the retirement age (*Germany) of normal people is a clinging to power problem.
It's only a terrible job if you want it to be we have more than enough government officials in the back ranks that miss 80% of sessions and get payed really well to just vote with their party. They should just have to retire when everyone else HAS to retire based on laws they introduced...
