You'd think so. But we're still in an age of software wizardry. It's easy to write great software if you exist within an organization where software dev. is already a core competency. But if that's not the case and you need to procure high quality software without already having the expertise in house then things get hairy really fast. Not that it's the best example, but look at healthcare.gov, it's a buggy mess at a cost of tens of millions of dollars.

I suspect that Brazil's home grown mail system is also going to be a buggy, low-quality mess at a cost of tens of millions of dollars.
