Many would be content with maintaining a sustainable, comfortable life. Today the general worker in developed countries is more productive than 40/50 years ago but gets less for it. Less and less middle class workers can afford to by their own house or apartment and those with lower paying jobs are barely getting by often under harsh conditions. Life should be getting better for all due to overall increase in productivity, but it's getting worse for many or is stagnating, while there are few who have been amassing obscene amounts of wealth and power.
