Especially modern/western, are total incapable to develop mudita, joy with the gain, happiness, of others, since not understanding, that fruits arise from causes, not understanding that one can not gain pleasing fruuts from unskillful deeds, not understanding, that fruits do not necessarily follow directly deeds, and even more not understanding release in the present.
So if they trace and bad done by a certain person, they can not approve gain of fruits pleasing to them. Wishing to punish, control... they deny that being previous deeds. Thinking that being are somehow inherent good, bad... they possible stay at biased creator-Godish ideas and go for ill-will all around.
This being the case, they have also, because projecting their imperfections onto all others, no ways to ever meet the Noble Ones, living "Gods", because can not understand how one, once "similar" imperfect, could gain sainthood.
With wishing that being don't gain what they had sacrificed for, by wishing of thieving away their wage, because of marxist ideology, modern/western people are total incapable to develop joy with others gains, when not personal profit by such.
It's impossible for a person with basic wrong view, with disregard to goodness, a person without gratitude, to ever reach the realms of the Brahmas not to speak fruits and paths.
Nevertheless enough space for joy with them, when sometimes joy arisesfor them even when just spread foolish ideas, not to speak of joy with them, once they are able to see through their huge defilements, maybe right here.
