Right now, millions and millions of the poorest people around the globe are being lifted out of poverty by expanding industrialization and capitalism. If you look at the "elephant curve" (ref. below), the only people that did not have rapid increases of income from 1998 to 2008 are about the 70% to 90% range, coinciding with the middle class of wealthy countries.

A common interpretation of this is that globalization has resulted in the middle class of wealthy countries now competing with the hungrier, more desperate residents of poor countries. This suppresses the former's wages and raises the latter's.
Capitalism will always have a "race to the bottom" to find the cheapest way to complete a product or service at the lowest possible cost. It can be exploitative, but it is not a zero sum game. With every passing year human society bootstraps itself into more wealth that is used to solve our daily problems.
To me, this is net positive to the world. The global poorest are in the most need of more income, and stand the most to benefit. Efforts at redistribution and charity, while well-meaning, pale in comparison to individuals working hard to better their lot in life. The middle classes are not suffering too greatly on net from globalization (their income did not shrink, it merely stagnated or rose less quickly).
It is easy to weave and popularize a story of middle class deprivation and suffering, because this story provides an interesting tale of the demise of bourgeois values- and who doesn't like that story? But in reality the economy is more nuanced than that. Maybe in some number of decades, the elephant curve will begin to flatten out as enough people rise to relative wealth, or cheap energy will boost the economy with gusto. Until then the middle class can wait.
