What right do you have to steal someone's property? Do the companies (or anyone for that matter) have an obligation to provide you with free or cheap stuff just because you need it? Do you let people steal your stuff because they need it?
This is not like stealing a computer or a car. The only thing the drug company is being denied is possible higher profits. The key word there is "possible". If the people can not afford to buy the drugs, then there is no profit to be made.
In the case of medicine, does the law serve a select few, or does the law uphold the good of the public?
I suspect that patenting medicine does both. Companies get to make money, while people get to live better lives.
But what do we do when people can not afford medicine? Here in the states the government provides TB treatment free of charge. That is because it is in the publics best interest that TB patients get treated. You would not want someone working at a grocery store coughing TB germs everywhere.
Why do public health clinics provide low cost vaccines? Because its in the publics best interest.
So what harm is there is some company making low cost drugs that the people would not be able to afford otherwise?
A valid law should uphold the good of the public before protecting profits of a select few. Drug company makes 400 million instead of 500 million. Ok, so what? The company still made money, people get cheap drugs, everyone should be happy.
But its not that simple. This is about the drug companies keeping a strangle hold on the people who need the medicine.
