查了一下,意思应该是：天天忙忙碌碌,挣点辛苦钱.
参考原文解释：
Quot.1897 links the form more days,more dollars to sailors being paid by the day:the longer the voyage the greater the financial reward.Later uses suggest that another day,another dollar occurs as world-weary comment on routine toil to earn a living.It has also generated a quantity of by-forms.
