Most good organizations will be suspicious of pure marketing claims unless they can be backed up with hard evidence. So yeah, they'll interview you based on that referral, but you still have to ace the interview. They'll hire you based on the interview, but they'll fire you if you don't perform well on the job.
How long is "eventually"? You only need a handful of years marketing crazy financial products to walk away with a fortune. The people who get found out aren't the ones who get hurt.
And yet, again, all the marketing in the world couldn't build one bridge. It just inherently cannot. Sorry.
Celebrities use drugs. Drugs are used in "cool" movies. You are even informed of the euphoric feeling drugs give you in elementary school.
The fact that "cool" kids in high school end up experimenting with drugs first is a form of marketing (even if it is organic.)
I have three words for your stupid "bridge" argument:
BRIDGE TO NOWHERE (http://en.wikipedia.org/wiki/Gravina_Island_Bridge)
What is stupid exactly about my "bridge" argument? What does the "bridge to nowhere" have to do with anything? That is just a Red Herring. All the marketing in the world will never produce any non-trivial feat of engineering. Sorry. Part of the issue is that you and people of your view want to point to marketing for the success of any idea; you have no demarcation criterion.
Oh yeah, and did you hear that new band at SXSW this year? Much better than the one I heard the other day on the radio.
