I think it's like how in sexual selection, many animals display traits that take additional energy to maintain. The theory is that this is selected for since if a potential mate is able to display these traits while still being alive and healthy, then that is some sort of proof of good genetics. If a company can put energy into looking sharp while also staying in business, that proves some sort of viability/success of the business. There seem to be a few qualities you could have to achieve this, discipline being one of them. But, even if it's discipline that's being used to look sharp, that doesn't mean it transfers to the work the business produces -- all we know is that they're still in business and are successful enough to look sharp. For all we know they could use shady practices, under-deliver, know how to protect themselves contractually, and extract wealth from large inefficient organizations.
