The equation he made isn't wrong, but it contradicts the fact that OP is criticizing people who agree with what they said themselves.

Data clearly shows a correlation between crime levels and average income in an area. Are we not mostly engineers used to working with data here? In fact, needing to "survive" is a common excuse used to justify the crimes committed in impoverished areas. Note that I said correlation, not causation. If someone has data that says otherwise, please provide it because I would be genuinely intrigued.
