The way Americans rationalize this is saying that if a business is not insanely profitable, then it is not even worth starting. In tech this manifests itself as saying that you should only create "world changing" businesses, and if you have a so-called "lifestyle" business you're seen as a loser. The reality is that these insanely profitable business can only exist when you have a deep pocketed investor as a co-owner of the business, that is, a billionaire owning a large part of the business is a necessary part of the process.

I do think this is closer to the truth even though you're being downvoted. I worked in the industry for about a year and I'm working on starting up my own company now.

If you removed the 30% tax credit, it would turn $3 a watt into the UK's ~$2 a watt. I know it's not that simple but it's not far from the truth. Even Tesla is trying to launch a product at $1 watt for commercial/industry clients.
