So now we know what happens when too many people who have too few assets buy too much house with the help of too many risky mortgage products and too little oversight. And while there's plenty of blame to go around -- unethical mortgage brokers, greedy bankers and irresponsible homeowners -- one culprit continues to get off scot-free: HGTV.

That's right. The cable network HGTV is the real villain of the economic meltdown. As the viewership reached a critical mass over the past decade -- HGTV is now broadcast into 91 million homes -- homeowners began experiencing deep angst. Suddenly no one but the most slovenly and unambitious were satisfied with their houses. It didn't matter if you lived in an apartment or a gated community, one episode of "House Hunters" or "What's My House Worth?" and you were convinced you needed more. More square feet. More granite. More stainless steel appliances. More landscaping. More media rooms. More style. You deserved it.

If you had any doubts about your ability to afford such luxuries, all you had to do was look at the 20-something couple in the latest episode choosing between three houses. Should they go for the fixer-upper, priced at $425,000? Or the one with the pool for $550,000? What about the one with room to grow for $675,000?

"How much money can these people possibly make?" I shout at my wife before wrestling the remote from her house-hungry little hand and switching it to the nearest sports program. "The guy can barely string together two sentences!"

And yet on episode after episode for this entire irrational decade, HGTV pumped up the housing bubble by parading the most mediocre, unworthy-looking homeowners into our living rooms to watch while they put their tacky, run-of-the-mill tract homes on the market for twice what they paid and then went out and bought houses with price tags too obscene to repeat. You couldn't watch these shows without concluding that you must be an idiot and a loser if you lived in a house you could actually afford.
