Devin Helton and BAP agree: the central problem of politics is the unceasing growth of third world slums.
Humans don't optimise for increasing living standards, they optimise for procreation. Humans who aren't willing to sacrifice living standards and civilisation for more children will be replaced by those who do.
This leads to the unceasing growth of favelas. Favelas are parasitic on civilisation: they appear on the edges of cities. They do not grow their own food or produce much (apart from a rich source of votes for a certain sort of political entrepreneur).
Favelas are populated by people who are willing to live at the highest possible density. They sacrifice everything for procreation, including producing beautiful buildings (their buildings are as cheap as possible: everything is sacrificed to make more of them). They occupy land that could otherwise be occupied by civilised people. They are a major source of crime, being proximate to civilisation.
What is the solution? The land must be confiscated and the people destroyed. Favelas will naturally appear and grow unless they are actively stamped out. We need a reconquista of the streets, violence against favela dwellers who enter the civilised areas and even those who don't.
