Bush has received a lot of the blame for our current recession, to the extent that Obama can still credibly lay the blame for the majority of our current economic problems at his feet.
Past a certain point, though, if the economy doesn't recover, then even a lot of the people who had originally blamed Bush for the economy will start blaming Obama. He inherited this mess at first, but if he doesn't fix it, he will eventually own it, to the point that people will blame him for it. Maybe that's an appropriate response, and maybe it's not, but that's simply the reality of how people will respond.
The same dynamic applies here. Even as much as I hate a lot of what Quesada and DiDio have done to comics, I'm not going to blame them for the initial downturn in comics sales that occurred at the same time as the downturn in the overall economy, and more importantly, neither did their bosses, because they could read the stock market pages as well as anyone else. That being said, down economy or not, there comes a point at which Quesada and DiDio's bosses WILL expect sales as a whole to go back UP, and it's going to be a lot sooner than the minimum three-year estimate that even upbeat economists are expecting it will take for the economy as a whole to recover. The comics industry as a whole was still in the shitter when Harras got fired - again, in relative terms, Marvel was actually doing quite well - but it didn't matter, because businesses do not stay in business by simply bunkering in and waiting for bad economic storms to blow over. Businesses who expect to survive by doing that will go OUT of business.
Now, Marvel is not going to go out of business just because its publishing wing is doing poorly, especially since its other media and merchandising wings are actually doing quite well, but if anything, that makes Quesada MORE likely to get fired, not LESS, because sooner or later, Quesada's bosses are going to say, "You know, even in this down economy, we're still making a fucking MINT on video games and movies and action figures of all these characters, and yet, the same Iron Man character who made multiple millions for us at the box office is barely even cracking the 50K mark in monthly sales." Businesses are not CHARITIES - they're not going to look at their HUGE sales GAINS in merchandise and other media, and then look at their CONTINUED sales LOSSES in publishing, and just shrug their shoulders and say, "Oh, well, it all evens out; we're making so much money through other venues that we can AFFORD to BANKROLL the floundering publishing wing."
