Is a national Bank bad ?

In short - probably.  'Probably' and not a definitive 'yes' because there's no saying it hasn't existed all along nor what side of it one is on, though I imagine 99% are on the wrong side.  Look at what people do for money and over money, why would it be common knowledge that a National Bank has existed since the early 1900's?

I wish I knew what you meant by a national bank because this question  is eerily similar to a classic US history question about whether or not a Central Bank was a good idea.  If so, yes it is.  It is just that the government back then recognized it was, but not how to organize it to solve the financial and economic problems they were facing and made some errors along the way and itself created a political football.

You see what corporations are doing to people who the president tells them to punish.  With a national bank, it would be control over you by your own finances.  Yes I think its one horrible idea.  Those corporation didn't even read GA's election rules law or they could not in good conscience have done what they did.
