Except the regulators first outlawed what is generally considered to have caused the great depression (savings banks allowed to invest, which translates to very, very rich people being allowed to take massive risks with poor people's money) ... then re-legalized it.

So not only are the regulators not going to allow things that cause another great depression, they're allowing the things that caused the first great depression too. They must want a rerun.

(Because if you don't allow this you're effectively demanding the extremely rich make good investments to stay rich ... and not even France, otherwise pretty socialist, dares to go that far)
