Foids control the supply of sex and affection.
Men control the supply of everything else.
Morally*,
-- Men are not "entitled" to sex and affection. True.
-- No foid is ever "entitled" to anything made by any man. Also true.
Now, the reality of the world we live in is:
The White knights and simps exploit some men (taxpayers, typically) in order to increase the amount of resources they control, and direct those resources to foids -- in part because simps can't help their urges to give stuff to foids, and in part because simps need this scheme to obtain female votes that keeps simps in power. They do it because it is their instinct to do it, and they justify their actions with "herd morality", that is: the set of contradictory beliefs that are pushed by cultural memes, such as the idea that paying tax is good, and that giving free stuff to single moms is laudable.
*(talking about universal morality in the philosophical sense, not the "herd morality", which is just ideology for NPCs to support the current fad)
