IMO, Right Wing posters are wedged when it comes to immigration: The seem to support big business and in particuluar those that agressively minimise their corporate tax.
On the other hand , Big Business has always been in favour of mass immigration to moderate wages, save businesses the expense of training and providing a bigger consumer base.
So, Right Wing advocates , particularly the working class Right Wing advocates are wedged: Support big business, rubbush trade unions and are anti-immigration.
One simply cant sup[port big business and be anti-immigration, IMO.
