Back in the day Christians took care for the sick and the homeless, they built orphanages and hospitals for the mentally ill. The amount of Christians didn’t decrease but the way these vulnerable people were cared for changed greatly. The more we have a society were we pay the government to solve these issues, the less we need charity.

I don’t know if Zakat-evasion is a problem in islamic countries, but I guess if we change the rules to get the billionaires to pay the ones evading taxes now will just change their tactics and continue to give a shit about the rest of society.
