I would argue that both type of thinking have their places. Some assumptions are no longer valid because of how the society has changed. There are innovations like internet, mobile etc. in the last 15 or so years that have had high impact on society. It is really hard to get the correct rationale behind practices, which can then be evaluated. Startups help in trying stuff and innovate. On the other hand, economic stability that allows these startups to actually spend this cash comes due to these established practices.
