I'm expensive because I'm experienced, not because of the technology stack. I would expect to get paid the same whether I'm coding in Node or Rails. Also, I don't think anybody is arguing that Rails can do things other stacks can't do; conversely one can also use React with a Rails backend. But I do absolutely believe that Rails generally provides faster development times, because it has pretty useful abstractions and components work well together out of the box. I can't say the same for Node. I think your point about devs either being Node or Ruby people is misguided. I did Rails for a lot of years, but have been doing Node for the past 2. It's not because I "made the switch", it's because the job I took was a Node shop. Knowing languages and frameworks is not mutually exclusive.
