I imagine people with children, among others, would have a hard time agreeing with this advice.
I mean yes, it's a rather sad perspective but nobody came with a solution to change the world yet.
Of course if we could all agree to shoot politicians, journalists and bankers on sight ... ;-)
It is my opinion that western civilization need a collapse before it can reinvent itself better (I hope). The power structures are so well entrenched that nothing short of said collapse can dislodge them (or let us do without them like they don't exist).
Unless I missed the point, and there's some reason I can't fathom why people with children would have a hard time agreeing with a reserve of foods and medicine.
