Harvey Specter got the long rope, Louis Litt was plain unlucky

I'm on my 4th rewatch and I understood this the first time I watched the show, but it gets more and more clear every time, does anyone else feel like most of what Harvey accomplished is simply not realistic ? He had Jessica's favoritism which meant he got away with literally everything (Even refusing to fire Mike Ross when she ordered him to, cutting her out of a deal with Darby etc). He preaches morals at the top of his voice, but crosses countless red lines himself. His arrogance and a is anger issues is different, but I would argue they would never exist, the rate at which he was pissing off people, he would've been humbled looong back. Is it even possible for sooo many people (incl Jessica) to take the fall for this one person ?? Even charisma cannot be explained to defend this long rope.
