Whats The Only Job That Gets A Pay Raise in A Recession?

If the congress wants to spend all the money in the world on gaining votes, we should deduct it from there pay check, but instead they get a pay raise. In 1989 the congress voted on a bill that would raise there salaries every year 4,700 dollars. How long will this go on? The congress should not be taking any more money from the taxpayer. This is insane.
