Moreover, Google made ~$15B in Q2 2018 in USA alone[2]. 86% came from ads, so let's assume Google made ~13B from ads in the USA in Q2-18. Even if we were to assume that each of the 240M internet users in the USA pays $10/mo to Google (an obviously false assumption), that is still only $7.2B for Q2-18, or half the revenue they are making from ads.

Because I have Youtube Red I don't have ads, and I can download videos on my phone. Except I can't really download videos, I just kind of cache them in an inaccessible format that randomly fails. Seriously, it's very common for me to go back to older downloaded videos and have Youtube randomly tell me, "well, it's messed up, we'll have to redownload it later."
On top of that, using Youtube Red means that I have extra ads for Youtube Red specific channels that I can't permanently get rid of. On top of that, using Youtube Red means that Google will occasionally decide that I'm not allowed to watch videos on my phone and computer at the same time, because that's "using the account in multiple places."
What I should be doing is using youtube-dl to auto-download playlists without ads and then sync them to my device. But I'm still paying for it, because... I don't know why, I guess I'm lazy. But there's very little reason for anyone to purchase Youtube Red when they can get a better, more private experience by downloading an ad blocker.
The problem is that Youtube offers both a free tier and a paid tier, right next to each other, with no signficant improvements to the paid tier. You're still getting the same algorithmic, eyeball-grabbing, buggy crap in Youtube Red. So I'm skeptical that this is a good comparison - if your goal with paying for apps is to get away from the dirty feeling of having someone watch you and manipulate you, Youtube Red is never going to satisfy that, because it's always going to be developed alongside the free version and it's always going to be reusing that codebase.
Compare that to something like Netflix. Do you think it's a mistake that they don't offer a free tier?
Also YouTube has all the music that people care about and given the success of streaming services I’m going to guess that its lack of success has nothing to do with people not wanting to pay.
I wonder if the products that Google and Facebook offer would actually be of better quality if they actually charged a certain amount to access their services. They have become so essential that I believe in most markets they could charge $5 to $10 a month and still retain a significant amount of users.
Then again, it gives them an excuse to not have to actually have a decent support staff.
