Assuming the accused is guilty and financially well able to pay for bail, this sounds like a pretty good deal to me to just drop some cash, write it off, and be able to leave and never show up for trial.
Assuming the accused is innocent and financially unable to pay for bail, they'll end up in jail without ever having committed a crime.
Like so much else in the US, it's showing heavy signs of a plutocraty, where money even decides if you'll be subject to the judiciary system or not. In almost any sane judiciary system I know there will be a pre-trial hearing to determine the likeliness of the suspect fleeing or obfuscating evidence, and only if this risk is arguably given, only then the suspect would be put in investigative custody (and that time served will be either counted towards the sentence, if guilty, or damages repayed to the suspect if proven innocent)
