Perhaps you'd like to give us an example?
Why should a believer take any notice of a rich man that has little chance of
entering the kingdom of God?
The conservative Christian Democratic party governing my country, for example. Many rich and influential people count on it to keep the status quo.
Both major parties in the U.S. Same situation, both operate based on Protestant values founded in what you stated.
It is true that wars between mankind often occur. I personally don't see
that belief in an afterlife is the cause of wars. Many wars have occurred between
nations who BOTH believe in an afterlife
That would be another example of the rich and powerful coopting your message. Armies were blessed. Bombs were sanctified. Spiritual messages were used as propaganda for very worldly agendas.
I'm not attacking what you said, just pointing out the social dimension of it.
