text: what does ''laissaz-faire'' refer to?   adam smith wrote the idea of laissez-faire, meaning "let it be"....he was a philosophe during the age of scientific revolution....he felt that the government only has 3 roles, nothing more, nothing less....protect from invasion, defend from injustice, and maintain public works....he also believed in capitalism...actually, we started studying this in my history class a few weeks ago....hope this helps
