Communism is a long and dangerous dream. Always has been, always will be.
But by my reading of the bible, it's very hard for me to accept that someone is a real Christian once they are retaining more than the median resources for the society in which they live.
In the USA median wage is about $50Kpa. A real Christain blessed by God with the ability to make more, and who keeps it, has a hard time explaining to me why they are not using that surplus for good.
But that's just me.
