History homework help

1st question- In the article “Adam Smith, The Wealth of Nations, it is mentioned that hierarchies favored mercantilism because profits were higher and it also increased the nation supply of silver and gold. On the contrary, Adam Smith believed in economic liberalism which included free markets and self-interest which would result in helping the economy. My question is what if any a certain point in the market, what if the economy were to crash, meaning people weren’t trading and selling any longer. How would the economy be if it were open to free trade? Would the sellers be struggling or the buyers? Or both parties?

2nd question-

The Haitian Revolution was a 13 year major event and yet it’s not a well-known historical event. Why do you think that is? Do you think because there wasn’t very much text found? Europeans hiding the horrendous things they did?
