Forum Post: how say no to banks

its so easy for goldman sachs to almost destroy a national economy, rating go down and governments need to raise interest rates on bond, because markets lose trust... i was thinking about action which could cause that markets and casual people lose trust to banks and Christmas its good time for that. a lot of money is on the move, from shops to banks, from shops to cash machines, numbers of transports is limited, between re-use this money they probably need to check and prepare money few times. so how many people need to take the cash from cash machines and bank branches to cause the effect of chain?? is anything similar possible? what could that cause? could the effect be stronger when in the same time visa, mastercard etc. will collapse again?
