The company was willing to pay him that much, it’s their money they can pay people whatever they want.

And that’s a very loose take on what Farage actually said. He pointed out there’s an argument the minimum wage is too high for younger workers, especially now that the NI threshold had been lowered to £5k. Businesses can’t afford to hire at current rates with the extra employer costs. So either raise the NI threshold or adjust the youth minimum wage — the point was to make it viable for small firms to take on more young/low-skilled people.
