I don't agree with it, nor do I understand it.
I see the same behaviour in corporate bankers are are earning many millions per year. It's OK to steal because I deserve more.
People like this are common thieves - and nothing more.
Growing up, my family went from poor to middle class. We did the hard yards. We never stole. Why? Because its about principals and ethics. Never, never excuse a thief. If your statement were true, i'd rip off the volunteer organisations that I _volunteer_ in ... because they don't pay me enough.
