What do you mean doubt? That people often choose to work more to afford more stuff is utterly uncontroversial. That's how the capitalist system is argued in favour of today.
On the other hand if you are admitting that capitalism forces people to labour under the threat of death, then it is an evil system, and morally must be eradicated.
Well it’s a nice utopian thought but not realistic.
Because of troglodytes like yourself. Here I thought you were asking in good faith. Serves me right.
