This is why I qualified my post with "at scale". I don't think there are enough qualified, technologically knowledgeable angel investors out there to cover a significant fraction of the startups that need funding. Keep in mind, also, that although the economy will recover, the glacial retreat of the 20th-century big-box corporations is a rather permanent state of affairs, which means that there will be a lot more people trying to start companies, while the number of wealthy individuals/angels will not increase at nearly the same rate.
