I am not defending bail as a system. However, the system in USA relies on it. The complaint here was not that poor people stay in jail. The complain was purely about someone being able to pay bail.

> About a third of people who are arrested cannot afford bail, while if you are rich (maybe through crime), you can pay it.

This means 2/3 of arrested people can afford bail or are released without it. A case of single rich person having affordable bail is not exactly proof of inequality here. Poor people who had low enough bail they were able to pay do exist too.
