Well, that's nice cherry-picking. Older people rise to the top in institutions because they have the requisite experience, patience and people skills, and yes, sometimes, brilliance.

Now, let's talk about the other 99% plus. Older people are throw-aways in society, and will be served, like anyone or anything else, when there's a buck to me made. Need I mention pharma? And forget affordable housing.

I didn't have the patience to wait for another university department taking 2 months to make a decision about hiring me, so I left. And so on for the other above-mentioned skills at other jobs. The demographics of institutions will change when the rules of the game change. The excitement of young brash startup culture either burns you out, changes when you are acquired (or go public) or your founder/owner/CEO decides that laws and regulations are "for schmucks only".

The demographics of government will change when rules change, for example, term limits, but then you'll see more job-hopping and inexperienced people being ineffective locally and globally.

Voter demographics are changing, as more and more angry seniors spend time yelling at clouds and forget to vote, and as young people object to people who "got theirs" already wanting to exert some draconian control over the lives of others who haven't.
