As much as I admire the founders of the country and the authors of the Constitution, I now think the founders were trying to do the right thing but made a massive mistake when they granted lifetime tenure to members of the US Supreme Court and other federal judges. They wanted to insulate the judges from transient political pressures, but in modern times lifetime tenure only makes the already undemocratic judicial branch even more unaccountable than it might be with reasonable term limits.
Chief Justice John Roberts did not exactly cover himself in glory for intellectual honesty in 2012 when he admitted that the individual mandate for Obamacare was unconstitutional but it still could stand as a tax even though the Obama Administration claimed it was not a tax.
Now Roberts is whining that Congress is not giving enough money to the judicial branch, pity the poor justices who have to scrape by on a paltry $223,000 per year, or the other federal judges with lifetime job security who eke out their year on only about $170,000 on the low side.
With all due respect to the judges, if you think you are underpaid, then quit your lifetime job with all the benefits, and try to find a higher salary with a private-sector law firm where you will have to generate new business called rain making, perform and keep track of your billable hours, and be accountable to a boss or senior partner for your time. Better yet, amend the Constitution to eliminate lifetime tenure and impose reasonable term limits such as 12 to 18 years as most other western democracies do for their highest court judges.
