Probably no effect at all.Religion is a virus and/or dillusion and very little if anything will affect it.

That's a good point. It probably would be less religious if that were the case. Too many churches that will help you out with food and shelter but will have a catch like having you listen to a sermon or something. People who don't know better and need the help start to think that god is good. If the government did more to fill this role, perhaps more people wouldn't credit religion for helping them.

It has been shown the biggest thing cutting the effect of religon is a national healthcare plan. People no longer feel the need for an invisible diety to preserve their health when they have a tangible program.
