it's always a problem of people wanting to believe something is possible (and mandatory to pursue) banging their heads against what is true and actually possible.
I'm not sure if you realize this, but change always seems impossible until it happens. 10 years ago it seemed completely impossible that Facebook would have 1B users, let alone the ~3B it has now.
The same 10 years ago it seemed impossible to that gay people would be able to marry, and even 4 years ago the idea of a Trump presidency was considered a joke.
Change is and will remain hard. That doesn't mean it isn't desirable nor does it mean that people shouldn't bang their heads against walls to make it happen.
