Joseph E Stiglitz

"Drug companies spend more on advertising and marketing than on research, more on research on lifestyle drugs than on life saving drugs, and almost nothing on diseases that affect developing countries only. This is not surprising. Poor people cannot afford drugs, and drug companies make investments that yield the highest returns."

Joseph E Stiglitz was chief economist of the World Bank from 1997 to 2000 and won the Nobel Prize for economics in 2001.
