One thing missing from the 'startups create value' argument is that some startups don't create much new value but simply absorb value from elsewhere by providing a more efficient lower friction way of doing something that was done in a different way before. Before I'm misunderstood, I'm not arguing that it's a negative result in the grand scheme, but it helps to be aware that this can actually lead to greater inequality if many people lose their jobs to a startup that only requires a handful of people to run it, where previously thousands were required.
