"All the capital employed in paper speculation is barren and useless, producing, like that on a gaming table, no accession to itself, and is withdrawn from commerce and agriculture where it would have produced addition to the common mass... It nourishes in our citizens habits of vice and idleness instead of industry and morality... It has furnished effectual means of corrupting such a portion of the legislature as turns the balance between the honest voters whichever way it is directed." --Thomas Jefferson to George Washington, 1792. ME 8:344
Quoting Thomas Jefferson on economics and finance is like quoting Mohammed on morality. He was clueless and being wholly owned by British banks caused him to go a little nuts.
Look to his greatest enemy, Hamilton, for wisdom in those areas.
