It's not villainy, prosecutors (largely) simply don't see promoting social equity as their job. They get paid to bring successful prosecutions. That's the metric of success and lots of successful prosecutions will advance their careers. If you can afford legal representation you get a lawyer who spends more than five minutes preparing to defend you. The prosecution is less likely to succeed, so the prosecutor is more willing to deal.
