One of the things I've learned about youtube this year is that it's an up to 1,000 + times advantage to be a beautiful, sexy woman that shows skin.
This means that they have up to a 1,000+ times advantage in terms of time & effort expenditure to get the same number of subscribers compared to a person that doesn't stand out particularly in terms of looks.
If you are a merely a pretty woman it can be "just" a several hundreds times advantage compared to a content creator who is just a young, above-average looking man.
Pretty crazy to see it all the time.
The main way male content creators can 'even the odds' is by focusing on a loud-mouth political niche, a temporary craze, or engage in social agitation.
Otherwise it's down to just content quality and pounding the pavement.
