I don't think that globalization or specialization are inherently bad; the problem is that politicians are pushing the process in ways that free markets will not sustain, and that are damaging the economies involved.

I'll start that I have a bias in that I believe the politicians pushing the globalization agenda are doing so dishonestly and for rent-seeking, do-gooding, or both, motives.

Two examples in America - the mass importation of illegals has a negative affect on American employment, especially when are exporting tech jobs overeas and already have a high population of welfare clients: also, the Corker deal to help the Iranians build a nuclear bomb, or as the globalists would have it, a "nuclear power program", ignores the security risks that giving Twelfer lunatics nukes in order to create baksheesh opportunities for the businesses that the globalists have financial interests in.

True and effective globalization will succeed when economies and nations can sustain them safely; right now it's just kickback and moral pomposity for politicians who think we are serfs to profit by.
