True enough in that he refers to the "cogs... falling on Brooklyn" as "seeds of the future, sown carelessly". But I don't think he specifically blames his father above anyone else. I think he actually highlights the futility of blaming anyone:

Interesting to note, though, that he excludes Janey. Superman he may be, but emotion runs through his logic. I'd go as far as saying that his detachment is merely a mask hiding the reality, its opposite - deep emotion that he's lost control of.
Surely estrangement fits that description somewhat nicely. He may well have been estranged from his father long before the accident - at least, that's the way I read it - because after the cog incident there's never any mention of the father until his death, completely alone.
It definitely seems to to place emotion as part of the answer, but that is also tempered by his understanding of cause and effect. The fat man started the chain of events towards the accident. Jon's mistake let him be locked in, and his father chose his profession which led to it all. As far as Janey is concerned, she seems to have has suffered enough for him to blame.
The fat man, and Jon's mistake were basically just chance events that are hard to blame in themselves, but the question is why he didn't tell his father. If he seems to blame each event equally, then there is still some blame to go around for all. Not telling his father was just that... he didn't have to, and some blame can remain.
