1. For starters you’re comparing TV production to YouTube content. The two aren’t even close to being equal in terms of budget.
2. Most popular content on YouTube still have at least professionals DSLRs and paid crew beyond just the influencers. Even if it’s just an editor or two.
3. I think the GP was talking about music rather then video content
4. Even with music, previously you’d have the record label pay for the studio costs, etc. What’s happening these days is that artists are generally getting paid less after deductions. Not before. That’s the unfair part.
