Why should it be? That's like saying that the $2.15 bottle of Coke you find at the counter should be significantly cheaper than the $1.99 two-liter in aisle 15.

Why should it be? That's like saying that the $2.15 bottle of Coke you find at the counter should be significantly cheaper than the $1.99 two-liter in aisle 15. It's not, and there's a good reason for that. A two-liter and a 20 oz bottle are completely different products, different people are buying them for very different reasons. They don't compete against each other, they compete against other products in that segment. On the surface, a 1000 sqft condo in the city and a 2000 sqft house are comparable products. But they're not, they are marketed to completely different kinds of people whose selection criteria are not comparable in the least.
