From my perspective it offers less. For instance, holding a passport from nearly any other country is effectively like holding a form of health insurance - if you get diagnosed with a long-term disease like cancer, you can repatriate and get free treatment. Not so with US citizenship.
Yet other countries don't charge for this much more tangible privilege.
Please cite sources. While we're trading unsubstantiated opinions; I disagree. I moved to a country everyone said had a crap economy and it has offered far more opportunity.
Of course, you're probably right. The real lesson here is to including supporting evidence and not just your feelings.
