No, it's particularly striking that a high-school age girl has taken the initiative to start such large protests and raise awareness about the issue and about the fact that something needs to be done yesterday. More generally, we find young people protesting and taking action against irresponsible, greedy, amoral "45-year olds" (as you put it) that yield the power and use it to enrich themselves at the cost of a trashed planet for the next generation.

I think it's pretty obvious what the message here is: the (older) politicians and business men are incompetent or corrupt, the powerless youngsters are showing themselves to be infinitely more responsible. It's a striking image.
