About 41% of the world's people are under 24. And they're angry…

One of the valid reasons for them to be angry at older people is for having made so many people under 24. It is hard to give a good life, in a sustainable way, to such a large population. Our population is living unsustainably and it is still increasing.

This is one underlying cause of many of the specific hardships that people are protesting about. The other underlying cause is inequality, which protects the privileged (and especially the wealthy) from these hardships by dumping them entirely onto the disprivileged and the poor.

Reducing inequality is a just cause, but we also need to reduce the cost of our existence, and doing that without making everyone poor will be much easier if we have fewer humans in the future.

Let's aim for 25% or less of the population under age 24.
