SO CALLED “good government” types hyperventilate and feign concern over the toxic effects of lobbying. (Never mind that it is a manifestation of the First Amendment right to petition f\the government.) Fair enough. If you want to drastically cut back on lobbying, eliminate taxes on corporate income, capital gains, and stock dividends. End the ability of adminstrative branch civil servants to, in effect, legislate from their cubicles. Require that all regulation come in the form of legislation from Congress. (And couple that with the oft-bruited-about requirement that all bills before Congress be limited to a single subject — no omnibus anythings, and no irrelevant amendments.)
As I say, if you want to get the money out of politics, get the power out of Washington.
