A little deflation because of progress is a good thing but sadly the average consumer often doesn't benefit from deflated prices due to corruption of one sort or another. Bitcoin lowers costs for consumers and merchants and resists corruption.
Edit: regarding price climbing until resources are exhausted, well the target is 'all the money in the world and then some' (due to progress)

I assure you, nothing resists corruption.
There is already ample evidence of corruption in Bitcoin, both in the early days and now.
Not that I couldn't see it happening Voodah, but can you give some examples of corruption in Bitcoin? Do you mean things like the pirate scandal or the recent inputs.io hack, or something more sinister?
