What are you talking about? You can't be talking about Denmark 'cause it wouldn't make sense. So, what can it be?
Interesting how you are willing to compare their taxes because it benifits your argument but you will discount other agruments and claim it's not a valid argument because of some silly reason. Economies of scale is a concept worth looking into. Also the overall size of the population in the USA gives increased bargaining power that we currently dont use. The biggest issues in making a comparison between Denmark and the USA is population density, rural communites make it more challenging to keep prices in check, but that's a problem that is easy to overcome especially if you factor in the benefits of bargaining power.
