A beggar,carrying a shabby old wallet,was begging alone from house to house .（As he complained about his fate, he kept wondering that people who lived in rich houses should be always unsatisfied, however rich they might be ,and they should go so far as to lose all they have .）
这段文字我的理解是：
一个乞丐拿着一个破旧的钱袋正独自挨家挨户地乞讨（不知道As怎么翻译）他埋怨自己命不好，（这句话也没有把握： 他不解的是那些住着高楼大厦的人们无论多富有，竟然都生活得不满意，更不理解的是这句话and they should go so far as to lose all they have ）

一个乞丐拿着一个破旧的钱袋正独自挨家挨户地乞讨,当他埋怨自己的命不好的时候，却总是能发现那些住着高楼大厦里的人，无论多富有还是对自己的生活不满意。真应该让他们也尝尝一无所有的日子。
