He doesn't have to say it when the fact that it was brought up speaks for itself. Of all the things in the universe, why was that particular thing brought up?
How does it feel to be right-wing scum without the backbone to even try to support your lies?
He brought up that prices in Europe are higher than they are here, which you did not dispute. You then blathered something about wages not being a factor, and he asked how much you would rather pay for a sandwich. It turns out you would rather pay poor workers $5 than rich workers $10, something that did not surprise anyone, even though you think you made a point by claiming the $5 would go to the workers.
I haven't seen evidence the prices in Europe are any different than here. Some right-wing fool running his mouth isn't evidence. There are over a thousand Subway restaurants in Europe and no one has mentioned their prices being high, based on the people who live there. The difference is, I've looked.
Let's take the UK for example. The minimum wage in the UK is 22.2% higher than ours. The minimum wage in Ireland is higher than ours and you can go down the line of countries in the industrialized world, or the countries of Europe, even though many set minimum wage by collective bargaining agreements and don't have a federal law.
The bottom line is the minimum wage in America is too low and even Canada is higher. If we raised our minimum wage to their level, I would expect prices for fast food to be a little higher, but that only means those workers are making enough to not get social benefits while working and the customers are paying them directly with wages being on a higher plain. That means the difference is totally one of perspective. The prices for Subway aren't higher when their wage base is higher. If someone in the UK is paying 15% more for a sandwich at Subway, why does it bother him if he is a minimum wage worker making 22.2% more than an American worker?
