Of course it's not sustainable.
The Western standard of living is based on access to near-limitless cheap labor and cheap resources from the third world, as well as a virtual monopoly on capital and advanced technology, research, science and industry.
Up until now the west has financed the relatively high standard of living of its underachievers with the proceeds of the global advantage it enjoyed due to that monopoly.
But the monopoly is on its way out, and we are now moving towards a global meritocracy. There will be a relatively small well-educated global elite, and a large uneducated global underclass.
