Salary Member of DPR

I just wanna share my opinion. I read at Kompas.com, there was wrote that salary  member of  DPR is Rp.54.907.200. *1.I hear at TvOne news that campaign costs to become member of DPR until Rp.10.000.000.000. if we calculate the salary  Rp.54.907.200 multiply 12 in one year and multiply 5 year, that equal with Rp.3.294.432.000. This number is so far from Rp.10 M. 


This case, I just calculate the salary. It is impossible the member of DPR do not need eat, etc. If we see the calculation the 5 year salary is not enough to pay campaign costs, So from where they get money to eat, pay campaign costs, etc?
