Actually pay is according to output. taxi uncle and admin give immediate results and get fucked if something screws up. Admin don't just staple and photocopy, those are researcher's jobs. Admin people deal with people whom the researchers pissed off along the way while thinking too highly of themselves, remind researchers of deadline to submit report to continue to get funding. Explain to sponsors if (which is almost always) researchers forgot and don't want to give report, and bear the kpkb from researchers who think they deserve the funding despite not giving reports.
Researchers are too fucking overpaid and underworked for their years of subsidised education wasting taxpayer money. They deserve to be paid 2k a month and cannot claim dinner, 2 shirts and 1 pair of socks from research funds.
