Consumerism is a moral disease caused by monetary inflation (which devalues money and therefore encourages spending).
Consumerism is a poison inoculated into society by socialists/statists of all parties. It is often associated with capitalism because it is only possible thanks to the abundance typical of this system of social cooperation, but it is clearly just the opposite.
"Capitalism is saving and hard work" (Miguel Anxo Bastos dixit)
When there is hard money (like gold or bitcoin), there is usually no consumerism. Fiat money promotes spending and discourages saving. The state monopoly on money is an attack on people's prosperity and freedom.
