I do attend a church regularly, and more than half of the people who attend regularly with me never contribute a cent. They are loved just the same as others who do contribute. The only person who knows how much is actually donated is the treasurer. I'm the council president and former treasurer, so I know of what I speak.
On the other hand, I have had friends that attend churches where the whole sermon is about giving money to the church. It was disheartening to them. However, just because it is this way in one, some, many or most, does not mean that it is universal. It is important to note that sacrifice is a part of most religions, in some way or another. The Christian New Testament has a parable about the widow and her two mites, and the rich man an his wealth. This is about sacrifice and not about volume. If you belief in something but are not willing to sacrifice for it, do you truly believe? Or are you there for some side benefit. You don't have to frame this solely in religion. Patriotism (whose concept was abused by our previous president), science, public safety and other noble pursuits are often characterized by sacrifice.
I my church there are many things required of us to be members. Only one of them has to do with money, and all of them have to do with helping humanity (note: not just those of my religion).
