Yeah, but the real ticker here is, we do not know what legal framework US used to have. Im betting dollers to doughnuts that it isnt by far a carbon copy of what the US has today. Infact, given the insetting lore, Id be surprised to see it be similiar.
I am very well aware about the money sink of the US political system. Whilst it does have some resonance in my region of Scandinavia, it doesnt at any lenght really compare to that of the US. However even here, the right lawyer, the right lobbiest, the right judge and the right place of a trial, can have a powerfull impact on any hearing, trial or political decition. I do not think it can be avoided, and strictly speaking from my own political viewpoint, I do not think it should.
Its not a shock to see the NCR functioning like that. Infact its a relief, its a sign of good writing that the ingame world takes a cue from ours. IT would be dreadfully boring and uninteresting if the NCR could go from pissant shady sands to fully fleshed out governance and statehood in such a short time, with the challenges facing the post apocalyptic US. Which is part of my point. The fact that NCR cannot have a fully fleshed out legal or even fiscal (banking) system as we know it, and that the US in the alternate timeline and this, is susceptible to lobbyists, powerbrokers and politicians, compounds my doubt about Heck being innocent. Its not a matter of "Get the fatcat capitalist" syndrome that my region of the world has a not undeserved reputation for. Its a matter of maintaining some critical sense and trying to see the NCR as it is if I was in it, not as I am as a gamer looking into it.
As for your last paragraph, there is such a thing as agreements. Thats the flipside. If Plebus has had reason to believe that he would be given some sort of respite or that the bank did not have a practice of immediately forclosing or demanding full payment at the risk of defaulting on the loan, then Plebus could very well be right in the fact that Heck bought his debt with the explicit purpose of driving him out of business. That might be more or less legal, but its certainly not something that will induce much faith in a banking system, nor is it good practice to change practice in the midst of an agreement. Not even in our timeline. It does happen ofcourse, and it does happen in our timeline aswell, but its never really percieved as being anything but applying blunt force to achieve a subjective goal.
Well, if you had an agreement with your bank that you had an extra few months to pay off your debts or that you were allowed some leniency in the comming months due to drought, sickness or other and the bank suddlenly foreclosed and tossed you on the street, you would be miffed aswell, regardless of the legality. Especially if your sister in laws rich hubby and their annoying brats who had allways coveted your propery took it over.
