> Are prosecutors dropping shoplifting charges for "upper middle class" people because they brought in an $1,000/hour lawyer?
Yes, they are. It's not this blatant, but the result is the same.
First, the rich person has probably been told, repeatedly, "Shut the fuck up, and only talk to your lawyer." This is a HUGE deal and helps your end result dramatically.
Second, the rich person likely doesn't have to worry about losing their job or coordinating child care while being missing for 24 hours due to incarceration.
Third, the rich person doesn't have to worry about making bail.
Fourth, you mentioned "social separation". Agreed. The richer person likely has a closer contact to a friend inside the justice system. That helps.
Fifth, a rich person is more likely to "look" not guilty. So both the prosecution and defense negotiate with that in their heads.
Sixth, the rich person likely knows English well and understands the cultural norms. This is a significant advantage. For example, in the southwest US, more than a few Hispanics wind up pleading guilty to having underage sex thinking it's not a big deal without realizing that they're about to have a felony on their record.
Seventh, the rich person understands navigating a bureaucracy. Do NOT underestimate this skill. A lot of lower class people don't realize the power that lower level functionaries have and wind up pissing them off to their detriment. The number of times I have seen people mouthing off to someone in the probation office makes me cry.
Finally, your lawyer likely knows the inside game. He knows that this judge likes to slam young punks, so he'll try to avoid him for stupid pot offenses. He knows that this judge is getting back from vacation on this day and is likely in a good mood so he can get a better deal. He knows that this judges hates DUI's, etc.
The list goes on and on ...
So, the prosecutor doesn't actually think: "He's rich, so I won't prosecute this so hard." But at every point where a decision can go for or against, there's a bit of bias in the rich person's favor distributed throughout the system.
Eventually that multiplies up to a big advantage.
