This debate is part of a wider 'globalisation' debate not racism.
For may years the economic and political mantra was that globalisation would increase global economic growth and improve the living standards of everyone. Well it turns out that for people who are in the lowest paid jobs that globalisation just means more competition for your already low wage job. Only the middle and upper class benefit.
For people who are educated, highly skilled and generally in professional service based jobs the global economy has been a boon. The price of consumer goods has fallen dramatically as Asian workers in sweat shop conditions drive down the cost of labour and put people out of work as factories close in our own country. That causes social tension.
Likewise, when the poorest and least educated East European workers arrive and drive down the pay and living standards of the poorest and least educated in our own country that causes social tension.
Its just a fact. The least educated and least skilled workers in the western world do not benefit from globalisation and the least educated and least skilled workers in the Developing World are working at barely subsistence levels of pay in dangerous conditions.
Most middle class people however benefit from globalisation.
ConsUmer goods constantly fall in price, offsetting inflation in basic commodities (e.g fuel). The cost of the coffee that goes in our latte in our local coffee shop may have gone up but it is served by a hard working East European graduate glad of a minimum wage job in the UK and we benefit as that minimum wage job keeps our cost down.
Our children are schooled in private schools or state schools with catchment areas drawing from leafy suburbs with house prices out of the reach of immigrants. We will never suffer from overcrowded classrooms with half the class speaking English as a second language.
Its not really about racism - for someone who has been unemployed or on unstable zero hours minimum wage jobs for years its about a basic standard of living and that is constantly undermined by every low skill low wage immigrant influx that arrives on our shores.
