By taxing bankers by 1% we can as a country make billions more for the future economy and for the future system. If the leading political parties follow this idea, the future system for the economy allows the government to put in more money into education , health care , employment and housing for the everyday working citizen. This further means that the government doesn't have to make those who can't afford their own living have to pay more taxes. Such taxes like the Robin Hood tax are great examples where this would work very well.
