It is probably not actually good for PG, because the majority of such people will fail and end up destitute, casting bad publicity (rightly or wrongly, doesn’t matter) on whatever start-up churner generated that outcome.

Additionally, founders who already come from wealth or have political connections, etc., are probably much more likely to succees in the financial senses that PG wants.

The only limited sense in which it’s good for PG is if there is a lottery winner he can claim credit for, a rags-to-riches story to whip up blind support for some ludicrous tech millionaire idealism.
