I mean not really? It ends on an incredibly bleak note where the banks got bailed out with no strings attached, one small-timer was prosecuted for fraud, every institution at every level of the economy abetted the fraud, and the big short-sellers who are our protagonists can't even take the moral high ground because they massively profited by betting against the health of the American economy which had real consequences for working people when it imploded. Kind of the whole point of the film is that the economic system is irredeemably corrupt and even trying to take advantage of their mistakes is intrinsically unethical.
