First, as I wrote before, it’s a fictional character saying this, and so the author’s intent may be to show the character’s bias, rather than to accurately analyze the US legal system.
Second, real people often have persistent complaints and rants that they repeat over and over because they get some kind of emotional payoff from it, and these are often not telling the whole story. These quotes sound like someone on that kind of rant.
For example, if you let me rant about my experiences with, say, US Customs, I might give you a pretty unbalanced rant… based on my own experiences, and with a point, but not a balanced picture of the whole situation.
Now, looking at these latest examples:
In the first one, what’s the context – a particular type of trial, type of defendant, and/or location? He does use the word “generally”, which means it’s not strictly an inconsistency, but it may be an exaggeration. (As people who are ranting often do.)
In the second one, again I don’t know the context, but I can think of two cases where it might make some sense. Either 1) if he’s talking about taking on a case of someone who can’t afford a lawyer, I think it has been common practice for states to provide a fixed fee to provide someone a defense against a criminal case. And here he has a point, which is currently being worked on. Since you seem to be interested in actual US law situations, maybe see for example this article or other search results for “public defender fixed fee”. Another situation, as I think I understand it, is when someone does hire a lawyer themselves, but the fees get to be huge if a case drags on. I think in this case, there is a contract between lawyer and client, that may also involve a maximum fee for the lawyer, or even if there isn’t, a client may become unable to pay at some point, but I imagine lawyers are required to see the case to its conclusion anyway. In that case, I imagine a large firm would have worked its risks into its fees and contracts, and tend to do as little work as it morally could (or, as they thought was good for its own reputation) after that point.
