To laugh all the way to the bank means to be happy about the money earned, but in this context the person is not happy about the money earned
Context: I would exploit the city's resources for all I could get and then be really shattered with myself as I deposited the money earned with blood and sweat.
Hypothesis: I would twist the city's tit for all I could get and then laugh all the way to the bank.

Given this context, is the hypothesis true (Yes/No/I don't know)?
