The biggest loyalty not being rewarded is with women. The female sex has an assets immediately at birth. Feminism ideology tells women to leverage this asset to maximum profit, but women are frankly retarded at long term planning. So they end up giving it away to men who they perceive as valuable. Which is decided emotionally and by what he can provide to her. The best way to counter this asset is with another woman which leaves you the power to walk away. Thus removing all leverage.
