Drug Pricing: Pharma Cartels?

Is there real price competition amongst MS multinational pharma? or are Cartels (Organization for Health Extorting Companies (OH-EC) :-) fixing prices? 

Can MS drugs keep getting more and more expensive? 
What do you think?
                               Flag of OHEC or is that Oh Heck!

Do Pharma need to engage more to try and explain their high pricing of drugs?
