Let me tweak that to add that the pay of members of Congress should either be abolished OR tied directly to the growth of the economy, as they do in Singapore I believe.
Also, a balanced budget amendment whereby all expenditures cannot exceed tax revenue. In order to borrow money by issuing bonds (or any other means of borrowing money) a two-thirds majority vote is required in both houses. In this way, deficit spending ought to be limited only to those emergency situations where most people can agree it is needed.
The balanced budget is a grand idea, along with the two-thirds required for passage to sell debt. I like it.
