What could your share of the national debt buy? The Ayn Rand Institute says 5558 iPhones.
ARI is using $199.99 as the price of an iPhone (16gb 5s). That is not what iPhones cost. They cost $199 (not $199.99) when you sign a contract agreeing to pay more money later. "Bill Me Later" type plans are not lower prices. The actual price is $649, meaning you could buy 1712 iPhones for your share of the national debt. (Which is still a ton, so why fudge the numbers?)
ARI's purpose is to complain about the large US national debt. By pointing out how big it is in concrete terms like 49 cars per American, they hope to help people understand it better. Campaigning for smaller government is a good cause. It should have the truth on its side. But using bullshit stats ruins that. Please don't taint good causes with irresponsibly sloppy, false claims.
In a competition with only true claims allowed, ideas like capitalism, liberalism, science and reason can win. In a competition of who can tell the most appealing lies, true ideas lose their inherent advantage. If you want to help promote the truth, stick to rational competitions only. Don't sanction irrational truth-ignoring competitions based around the most shocking headlines, popularity, social status, etc...
