If this can't be done at present, at the least the voters can be educated not to accept bribes, so that vote-buyers will spend a great deal of money but will find they can't be elected. This is the only way people will stop thinking that to compete will require ever-increasing amounts of money.
如果目前做不到，至少要教育民眾不接受賄選，讓賄選者花大錢卻選不上，這樣大家也才不會惡性競爭，愈花費愈多。
