I would criticize the line more directly, in that it's typical silicon valley magical thinking. "The rest" means the slightly-less-wealthy, because these "financial opportunities" are only useful to people with large sums of spare cash. The line reads like a populist appeal, but working class people aren't sitting on HN thinking "finally, improved investment opportunity!"

It's par for the course so I don't mean to call out this person directly, but I'm hitting that point where I don't feel optimistic by default with these claims.
