But Economics uses mathematics. Not for proofs (although some misled academics disagree), but for understanding of prior performance.
The real disaster is that mathematics is increasingly using economics and other social sciences as a filter for what is permissible to be calculated. :/
Hypothetical scenario: you calculate that people from country A are twice as likely to commit a crime in country B when compared to native citizens of country B. Ok. What do you do with that? I'll tell you what you don't do: you don't round up everyone from country A and kick them out and justify it with "mathematics." That is an incomplete view.
Perhaps I'm sorely misunderstanding what problem you see so please correct me of that's so.
