Can't it be shared-fault? Most of our residential area designs suck and discourage taking children outside without cars or at least buggies.

Yeah. Fuck those poor parents already living under the stigma of not being able to provide for their kids as the world is driven ever more to shit by people with an “I’m alright Jack” attitude.

We banned smoking adverts and that helped.

Can we take collective responsibility for our society without taking any collective blame?

Need to split it out. Take out the blame and punishment, and see it from a grown up point of view.

Coz I hear you, I'm not taking the blame for stuff I had no control over. That makes no sense. I owe nobody anything for that stuff.

I am over okay with taxes, or other measures, which address society's needs even if they aversely affect me. Ws we have a shared responsibility to make society a better place.
