Mismanagement, greed and selfishness has eaten to our core
We bleed and sweat greediness even from our pores
Some people are slobs for love, some for wealth, some for power. This is a trait of people. We won't be able to significantly alter human nature at this time, in my opinion. Libertarianism doesn't make this claim in any way.
Sadly, we can't alter the ways of humans and that's why the world is in the state it is in. We can just hope for the best.
