Oh, please. Don't be stupid. If all the people you're alluding to, including everyone with 300K, 400K, 750K, etc, lose their savings, then everyone everywhere withdraws all their money from all the banks to put it somewhere else - including under their pillow, dumb as that might be. People keep their money in banks because they trust banks. No more trust = no more banks. Capiche?
What happens then? Do you really need your hand held through this? If you're advocating another run on the banks - another 1929 Great Depression - then you're a fool. If you're not advocating that, then what the **** is the point of your questions? We don't need another collapse of the banking system. Period.
Get it? Or do you just refuse to get it because there's some idiotic ideological point you seem desperate to make? If that's the case, then spare us all, because you've failed to make it.
Yeah ..... you should go pay the mortgage on someone's third home. Let us all know how that works out for you.
