Have you deployed to a data center recently? Like, any data center anywhere? Unless you're in with people doing really bizarre, high-download stuff.. How about how about Amazon's AWS:
Data Transfer IN To Amazon EC2 From Internet $0.00 per GB
You can saturate your download speed 24/7 and they won't charge you a penny, whereas "Data Transfer OUT" starts at $0.12/GB, past the first GB.
In any event, there's this thing called supply and demand, which says (among other things) that prices of products are set completely independently of their cost.
These prices are what determine costs, and where to most effectively allocate capital (being servers, households, or routers alike).
