Whether in America or Britain, working-class people only matter when immigration is an issue

On the one side stand Silicon Valley moguls and leaders of corporate America; on the other, longstanding Donald Trump loyalists and supporters of the Maga (“Make America great again”) movement. One side claims to be building America’s bright new future by recruiting the best talent from across the globe, the other to be defending US workers from the depredations of global capitalism. One side portrays itself as challenging racism and bigotry, the other is outraged by bigoted views of American culture.

The H-1B visa – which allows US companies to hire foreign workers with “highly specialised knowledge” – might seem an unlikely spark for a mini civil war among Trump supporters. Yet the bitter feud that has gripped the Trumpsphere over the past week has exposed many of the fissures of US conservatism. There is little to admire on either side and much to deplore. Both sides are right in certain respects, but usually for desperately wrong reasons.
