I work as a contractor these days. I find the teams with top spec macbooks have terribly bloated code bases, because they don't notice. Pulling into the project with my laptop with 8gbs of ram instantly recognizes the bloat. I point out the things they are doing wrong, and they typically know, but haven't cared to fix the issues. They end up wasting a mountain of money in production and ironically become very cost sensitive about hours worked instead.
