"As Jon Cruddas’s inquiry into the dismal 2015 defeat found, Labour is now toxic with more socially conservative voters who are concerned about immigration, welfare, patriotism and Europe. Of those voters, Cruddas found that an overwhelming number consider immigration the single most important challenge facing both the party and the country.
But even though this problem was flagged long before the referendum campaign began, Labour’s leaders and the bulk of its MPs don’t actually seem to understand why so many Labour voters are anxious about immigration: first, competition in terms of jobs and the downward effect on wages; second, the impact on public services and the allocation of social housing or welfare benefits; and third, the loss of tradition, culture and community. Among Labour’s old supporters, the second and the third reason are the most significant."
From the article. Not exactly the sort of people that would vote labour anyway.
The second paragraph is just myth. There is very little downward effect on wages. The impact on public services is positive, as so many immigrants work in them, and add to the pot. If our culture and tradition are disappearing, it's our fault for not making more of them. I prefer a mix of culture and tradition anyway. Loss of community is because of a loss of community services, lead by the government cuts, and not caused by immigration.
"Between 2004-2006 and 2012-2014 the ratio of foreign-born to UK-born workers rose by about 8% in low-skilled and semi-skilled service occupations across the UK as a whole. This was the largest change in any of the four occupational groups classified by the report.
So for a low-skilled or semi-skilled occupation paid £8 per hour, this would work out to a drop of between 1 and 2 pence per hour, each year.
Many issues have an affect on the wages of the lowest paid. Academics commonly list global changes in technology and trade, or national differences in education, attitudes to gender, and union activity as having a much more significant effect than having a higher proportion of immigrants in the workforce."
