Anti-UKIP Propaganda?

[a completely inoffensive name]

So you want to raise the wages to levels that the British would do those jobs for? But then the prices would go up, companies may become uncompetitive with companies from other countries and your own poor(er) people would complain about the price of groceries rising a lot.
And due to this price increase, the benefit of the now higher wages may just get nullified in the medium/long term so that people won't want these jobs any more.

This is an argument for never raising the minimum wage.
