What was the general demand during the American and French Revolutions?

During the French and American bourgeois revolutions, there was widespread demand for a revised tax policy. The American colonies suffered from high duties and tax costs in favor of the mother country. In France, the third estate was subject to large taxes, while the aristocrats did not pay them. As a result, hopes were pinned on constitutional and republican institutions, which were supposed to develop tax policy in the interests of the majority (or at least in the interests of the bourgeoisie).
