Nothing lasts forever. Having said that, the number of bootstrapped / angel-funded companies sitting there cheerfully producing a large-enough-to-be-useful profit for years on end is pretty huge. Others have given examples in other replies to this comment, but I just wanted to point out - they're not outliers, they're a trend. The claim that the model doesn't work is rather easily falsified.
