Most religions give dick squat back to the Governments which grant them such benefits.
There is no free lunch -they say. It can be observed when a particular religion is reaping fat, one of its members holds public office or sometimes a religion influences members to vote or take a political position or someone that wants to get elected slants towards a particular religious majority. Religion serves a political purpose and although it does not pay taxes their followers do and buy products and services.
Take for example the WT, they are non-political so they do not get any favors. What they have, they fought for. But they buy paper and services and other goods and employ companies and law firms -and that is big business. Take paper for example that they buy or bought a lot of in the past.. Those companies that sell to WT do pay a lot of taxes and employ people who the gov extract taxes from etc. So although WT does not pay taxes directly in a way they do so derivatively. But notwithstanding the taxes, WT is a big customer and those wt suppliers are enemies with WT enemies not because WT has secret deals with them but because WT is their bread and butter. WT doesn't print much as they used to but they are still a major customer to their suppliers Other religions too that do not pay taxes do benefit the government -until they are not needed or are more of a problem than an asset. Just my guess on this. I do not know.
