I really respect the author for going against the grain this much. I'd like to distill some of the points it makes, because the intensity can make it easier to treat this as an all-or-nothing:

[Ideas posited] 0. Companies that fail rarely fail because of delivery speed (e.g. yahoo mail vs google mail).

1. Investors mistakenly believe working harder is the key to startup success.

2. Investors also have a financial incentive to objectify/manipulate workers, even when those very workers may have negligible equity often they are put under more pressure than the investors themselves.

3. Mission-focused-talk is likely to be disingenuous because investors know most companies will fail, and those mission statements are lofty anyways.

I largely agree with each of these points, however I think the attitude is too gloom-and-doom. If you stay late at work, it's because you chose to. If you're afraid of losing your job if you don't, that's because of market forces.

I also believe that working smart rather than hard helps the investors as much as the individual, so there is a win-win if people are open-minded to it.
