A proper analogy would be something like two crimes, A and B, both with the same statutorily defined maximum penalty--life imprisonment--but where the typical sentence for A is much less for B. The defendant is found guilty of A, but the judge uses aggravating evidence to sentence them as-if it were B. But that highlights the fundamental problem: why would we have both A and B with the same maximum penalty, both covering the same or similar behavior? Often the point of A is to make convictions easier because proving B proved too onerous in practice.
What we want to get back to, and which almost every other jurisdiction implements around the world, including both systems thought to be far more fair than ours as well as less fair (for different reasons), is to have better tailored crimes, including penalties. One of the reasons we have so many felonies these days is because sentencing someone to jail for a single day on a misdemeanor offense for stealing a pack of gum for the 20th time can require a jury trial just as onerous as a felony offense with a 20 year sentence. Thus, if you want a more fair system, we probably may need to make it easier to sentence for smaller crimes with lighter sentences. IOW, lower the stakes so there isn't an arms race between punishment severity and procedural protections.
Most countries don't even require juries or panels for serious crimes, let alone light (i.e. misdemeanor) offenses. The shift to granting jury trials for any offense carrying possible jail time started in the early 1900s via Progressive Era reforms. Today only NYC (just NYC, not New York state) and, I think, South Carolina are the only jurisdictions[1] that don't grant a right to jury trials for misdemeanor offenses with jail time as a permitted punishment. Some other states nominally only provide for juries for 3+ or 6+ months of jail, but procedural precedent has resulted in courts effectively extending the right to any offense carrying jail time.
Note that the city of San Francisco has had for decades a public defender's office with equivalent or better resources (time, money, expertise) as the prosecutor's office, but the city sees the same interminable cycle as everywhere else.
[1] Also I think Federal jurisdiction, but purely misdemeanor cases without the threat of felony charges at the Federal level are pretty rare.
That's part of the point. The maximum penalty for many nonviolent offenses is absurd.

But why is this a problem? The purpose of the trial is to deter the other million people who would have committed petty crimes if they weren't prosecuted. It doesn't matter if the trial costs ten thousand times more than the value of the stolen goods. Moreover, if the sentence would actually be one day then guilty people would just plead guilty without coercive plea bargaining because it's less trouble to serve one day in jail than to waste two weeks of your life going through a trial and then serve one day in jail anyway.
Whereas if you're innocent you may very well be willing to spend two weeks at trial to clear your name, vs. the status quo where if you try to do that you'll be charged with a dozen vague offenses that everyone commits in the course of an ordinary day but are only charged against people who demand their day in court instead of accepting a plea for some other offense the prosecution isn't sure they can prove, all of which have coercively onerous penalties.
