As an older person, I'd say the younger generation is worth more than others. I want to prioritize young people's futures over mine. The opposite -- sacrificing the next generation's well-being for mine is downright criminal and an abuse of power.
Of course, it's not a dichotomy. I think we can both have reasonable welfare.
I took it to imply that the youth will have to live with the consequences of this vote for a much longer time period than the majority of folks who voted to leave.
The undertones in this point imply that votes from the young generation is worth more than others.
