Good argument. I think such bottom-level corruption is caused by top-level corruption and general demoralisation of society. When you have low-level worker who is corrupted, but higher-levels are moral, you can just denounce that one worker. If higher levels are also corrupt, you have no one to appeal to, so corruption thrives. So, fixing corruption from top should be first, but then low-level corruption should be stamped out as soon as possible.
