And yet I know MANY that have, so clearly this is a completely false statement.
Maybe that's because most of the Middle Class is capable of understanding that they aren't getting a fraction of something? Right now $1 will get you more than 1,667 of something (satoshis, the spendable unit of the Bitcoin currency).
And not only that, the OP contradicts himself. It doesn't explain that he says middle class people won't pay that and instead we have to believe that someone poor is going to pay $60 for 1/1000 of something.
Clearly those who understand Bitcoin invest in it for its intrinsic properties, and on the basis of the money they can invest, regardless of what fraction of Bitcoin they can buy at that moment.
