I'm from the UK so have to pay through the nose in taxes for the NHS to be ripped off by the pharmaceutical companies.

I doubt very much anyone in the NHS negotiates a competitive price for Lovaza hence the need to remind people that it's probably better and more effective to buy your own from USA online discount providers. Even with the postage it works out cheaper than UK high street providers. But we have the same attitude here.
People say "Well I pay my taxes why shouldn't I get everything free on prescription whereever I can? Why should I care if the NHS is being ripped off?"

But the fact is that money is limited and services are cut to fit the budget available.
If you claim for stuff you don't really need then can't get treatment your do actually require whose fault is that?
Just because other people rip off the system is that any reason for you to do the same?
