Gresham’s Law: bad money drives out good when people are forced to accept both. They hoard the good (scarce, stable) and spend the bad (inflated, manipulated).
Thiers’ Law: good money drives out bad when choice is free. The stronger currency - scarce, incorruptible - naturally prevails.
One thrives on coercion, the other on freedom. Money reflects trust - the better choice always endures.
