Making bail a multiple of something like gross total income and remove the need for the judge to set a dollar amount should help. So basically instead of saying "Bail is set at $50000" the judge can just say "bail is set at X month income or Y% of net worth" without having to take any consideration of the accused financial situation into account . Of course you'll probably need some minimums and few other tweaks, but on the whole it feels like a better method.
