Wealth is not taken from our consumers and given to Sam Altman. Sam and his company are creating wealth - increasing the pie.
Of course it benefits everyone while also benefiting them.
Wealth need not be redistributed to improve lives. Just the mere invention of ChatGPT and letting people purchase it and use it is enough to improve people’s lives. Redistribution does not solve any poverty problem other than transfer power.
Sam redistributing money will not sustainably change anything about prosperity or poverty.
