The money isn't "in the bank" until the end of the day when the deposit is made.
The tip-jar isn't emptied into the bartender's or street-musician's pocket until the end of the night.
The till is owned, as is the tip jar, they are not public property.
If I leave someone an upvote, that's essentially a tip for that specific post and that specific account.
Again, I will explain. Your tip isn't immediately from the pool to the post, it is earmarked for seven days and no, it isn't for a specific amount at all. Your vote percentage might be static, the vote value is not and will be affected by other things like how much the amount is on that post now. For example, if your vote is 10 cents on a post with no other votes, it is 10 cents (affected by all other votes of course in the system having an effect on the pool). However, if a large voter comes in and adds a vote on top, your vote might be worth 20 cents. You can test this by for example, voting on a zero voted post, and then voting on one in trending.
For whatever reason, you seem to be quite emotional about the mechanics here. However, consider if YouTube allowed all uploaders to decide how much of the money they pay to content contributors they get. Do you think it would accurately represent value if left unchallenged?
