In the early 1990s, James Goldsmith wrote a series of books among is the "The Trap", a profound piece of work that foresaw the effects of free trade and globalisation on income inequality:
"Nations ... cannot allow themselves
to be overwhelmed by immigration
otherwise they will lose their identity
and cease to be nations." - The Trap
The 1st section of the book discusses the flaw of using GNP and economics as a measure of quality of life. The 2nd section criticises a number of capitalist dogmas - among them is the belief that free trade is always good. In this section he wrote the devastating effects of free trade (and cheap 3rd world labor) on the working and middleclass of Western societies unless govts take serious actions to mitigate these effects. The 4th section discusses immigration and how much immigration a country should allow:
"...nations need new blood and new ideas. But they can only absorb a limited amount at a time. They cannot allow themselves to be overwhelmed by immigration otherwise they will lose their identity and cease to be nations. Newcomers who are welcomed into a nation should want to honour and respect the customs of their new home. They must not step on shore or over the border and reject the national culture. If they do, the inevitable results are hostility, intolerance and conflict" - The Trap, page. 59
