> I believe future CPP payouts are based on contributions made today. This is unlike the US social system where current payouts are based on contributions made with today's generation of workers.

I think you're conflating the basis for calculating the payouts you will receive, and the sources of payouts. I. e. most government pension schemes are use today's payments for today's pensioners, but will still give you a higher pension if you paid more/longer into the system.
