When two friends have a common purse, one sings and the other weeps. 当两朋友公用一个钱包时,一个唱歌另一个哭泣。
The common cause of all these calls on the public purse is the gap between the responsibilities government is thought to have assumed and the powers and competence government has to discharge these responsibilities. 之所以出现这些要求公众掏钱的情况,其共同原因在于,在人们认为政府应当承担的责任和政府为承担责任而应具备的权力及能力之间出现了差距。
