Inequality has increased but poverty has decreased. The world is so much wealthier now.
Yes high inequality is a problem but I'd argue too low inequality is a problem too. You need a difference of outcomes to motivate people. If that doesn't happen in currency it will happen in another way. For example people will invest in political power and work hard to corrupt the system in their favor. This happens with high levels of inequality but is reduced as there is a legitimate path to improving ones lot. There is something competitive in us the drives us to do better than our neighbors. That needs a legitimate outlet.
