This is not a good financial analysis. Nearly any mature company would absolutely pursue 0.6% in cost reduction. That is a huge, juicy target.
Because scams destroy trust in institutions, and trust in US institutions is already worryingly low. Without trust in institutions the system collapses.
The US GDP is more than 27 trillion. If 158 billion is being lost. That's about .6% of the GDP. So, my question is, why does this have to stop? If it is stopped the benefits to the global population seems trivial. I'm sure at the individual level it is devastating. Good luck getting the national government to care about such a small percent.
