If you are a business in a competitive industry, and you have an equivalent size competitor down the street (or in India/China), then your priority is cutting costs so that you can cut prices to stay in business, so that you can pay people.
If you decide on a moral front to keep unskilled workers on a wage which is higher than your competitor, then you will go out of business in the medium to long term. End of story.
If somehow we are NOT talking about a business in a competitive industry, maybe an colluding oligopoly, which is trying to maintain its market share then these laws might be absorbed in a closed economy, but due to those pesky people in other countries also wanting to make a living we have a choice.
We could throw ourselves into the EU, becoming PRO-EU

, leading to the instictive protectionism of the EU against the rest of the world, or we could continue our support of free trade and the free movement of workers, giving a more equal opportunity to many around the world.
Of course if you decide on the protectionist route then you leave yourself open to the accusation of many nations such as the Arabs that the West is united against them (therefore jihad), also you might find that they raise barriers to trade themselves leaving the net effect the same or even against you.
Of course you could take advantage of any natural disaster and attach conditions such as opening markets to the aid which happens a lot, but then you'd be with the status quo again
