Youtube got to its current position not by lowering prices but instead by Google making sure that Youtube videos are returned at the top of Google search results. Competing video websites don't have this advantage.
Plus the early days of google (before youtube acquisition), i dont think their video search was as good as the text search anyway (but i might be misremembering of course...).
The video results for most of my queries are like 90% SEO garbage without a video even being present on the linked page.
It's abject failure.
