Nation providing goods and services procure wealth from other nations and nation providing merely labor and markets merely spend its wealth and transfer to its trading partner. Thus, global trade order globalizes the classes and have- nots. Free- flow of goods and services and money and ownerships facilitate flow of wealth to the top and flow of misery to the bottom. Trickle-down theory in national level operation make rich richer and poor poorer and poor people at the mercy of trickle down effect. Globalization of this theory is allowed by globalization of trade which makes rich nations richer and poor nations poorer.
Consumerism is nothing but expenditure of wealth in exchange for life-style.
When consumerism is confined within a nation, there is wealth transfer among people but nations as a whole does not loose wealth. But internationalized consumerism transfers wealth from consumer to the producer across national borders. Some nations acquire wealth and some nations lose it. Even the new employment gains by international trade are short-lived. These gains are spent right back on giving greater boost to consumerism.
