Taxation of Religious Organizations

I've always thought that religious organizations have been somewhat corrupt. I'll keep it short. I'm sure a decent percentage of you folks here in the USA think it's kind of ludicrous for Churches of all religions to be able to avoid being taxed which in return allows for the pastors of mega churches/mid sized churches to gain massive amounts of wealth. I know that's not the only cause but it just doesn't seem fair. I believe it's about time for that to change if possible. I know there are plenty of people who don't agree but I'm not talking to those people. I'm talking to the people who agree. Let's make churches start contributing because there is no excuse!
