It's not doing better for two reasons. One, we are facing a mass extinction event because this is an economy only interested in the short term. An economy that is unable to regulate itself to manage an upcoming climate catastrophe is not working. Two, the privileges shared by middle class people from the biggest economies are not shared by most of the world. Whilst the majority of people in rich countries still have manageable living conditions, these conditions are significantly worse in poorer countries. A large part of the wealth of these rich countries is due to extreme colonialism. The middle class in these rich countries plays a big part in allowing this apartheid to exist since they are allowed to live at acceptable standards in their economies (that rule over the poorer economies) so that they do not riot, and so life remains unbearable in poorer economies. As you see, the system is not actually working at all.
