I don't know how that's an insult, but whatever.
I can't believe this thread is still going, when you ask the same question and argue the same thing, yet you keep getting different responces as to how it's fine as is. The thing is, you underestimate Mexico/US a lot. I don't know what else to tell you.
In a dream world, sure Mexico and the US would be in the CONMEBOL for a 'better challenge'. They would have no problem qualifying, and the small teams like Jamaica/T&T/Cuba etc. could qualify from the CONCACAF. Would that make you make another thread about how they need a better challenge? I mean, that's your argument, right?
If small teams getting into the World Cup really bothers you, you have to look at Africa, or Asia. What have they done? (besides Korea, we all know what they did). Africa has five teams in the World Cup and all but one is eliminated already. Asia has teams like Saudi Arabia getting beat 8-0, 4-0 in World Cups, but there's no thread about them. CONCACAF isn't that bad off. In fact, besides Costa Rica, the others have a chance to qualify to the round of 16.
