No, it's not far cheaper - it just has a different way to compensate its processing costs. In fact, without even considering Coinbase fees, it's still more than credit cards: https://blockchain.info/charts/cost-per-transaction-percent

That's misleading: A lot of those transactions are microtransactions (not possible at all with credit cards) so of course the % will look elevated.
Dwolla has free micropayments (up to $10). Amazon offers special pricing for micropayments (5% + $.05) and so does PayPal (although it requires a separate account). If BTC price goes too high, the dollar costs of Bitcoin transaction fees will get pretty high as well. Anyway, here's an interesting article to read: http://www.bloomberg.com/news/2014-01-02/bitcoin-is-an-expen...
Like others, you seem to be assuming that bitcoin is static and not being improved and that transaction fees won't be lower with continued technological improvements.
Can you explain that graph? I have no idea what I'm looking at. Where are these fees going?
Bitcoin miners.
Simplistically: Each transaction can optionally include a fee as an incentive for Bitcoin miners to include the transaction in the block they're calculating. Right now, blocks can produce new "mined" Bitcoins, so the reference implementation doesn't frequently add a fee as the incentive to calculate a block is still quite high. As the "mining" (new Bitcoin creation) rate declines to zero, fees will become more important as an incentive to continue calculating new blocks.
https://en.bitcoin.it/wiki/Transaction_fees has a complete explanation of the current reference implementation of fees.
