AFAIK, in the less-civilized states it's not expected that most people will pay the entire bail amount directly. The standard course is that they put up 10% or so (and the judge sets the total amount expecting this) and call a privatized "bail bondsman" to put up the rest (and charge a hefty fee). You see, it's more fair this way, because you have a choice of which entity will screw you sans trial.
