Why was Jefferson's decision to purchase the Louisiana Territory considered by some to be hypocritical?

Thomas Jefferson certainly acted in a way that was contrary to his political beliefs when he agreed to purchase the Louisiana Territory from France.  However, this does not necessarily mean that he was a hypocrite.  It is not necessarily the case that political leaders should stick fanatically to their principles even when it would be better for the country if they were to bend a little. Jefferson believed in a strict construction of the Constitution.

based on this information, i would advocate against sweatshop labour because it exploits workers in unsafe working conditions with little pay. though sweatshops produce inexpensive goods, they harm the environment, workers, and often use unsafe materials to make consumer goods.
