This is contradicting the neoliberal mantra, that it is totally the individuals fault and thereby justified.

Sorta. But anyway, neoliberalism is far from the only oppressive ideology.

Also Islam with its prohibition of interest is incompatibile with capitalism

I really don’t think so. Interests are not really a foundational pillar of capitalism. Private property of means of production is.

obey God

And did god (or gods) speak to them? Or there is always a translation layer that includes other people; prophets, messiahs, clergy, shamans, visionaries, etc.? Still a hierarchy. Still a means of control. Who decides what the gods say controls people. That’s exactly the problem with religion.

About the soviet union and other antireligious countries: there are multiple ideologies that can lead to oppression. I am definitely not going to say that without religion oppression wouldn’t exist. I am saying that religion is an enabler for it.
