I discovered a cruel secret: the money earned from working is not enough to pay for medical treatment.

Not working, you can't spend much money;
Only when you start working do you realize that eighty percent of your expenses come from working.
The hard-earned money,
In the end, only twenty percent remains, and it has to be used for medical treatment.
After calculating inside and out,
You haven't kept a single penny,
Once it passes through the boss, it all goes out.
Not working, at most, you're just poor.
