The only thing that makes manual labor worth more, is demand. And adding more competition to the market does the opposite of that. If anything, robots will make human labor even cheaper. And that will only get worse, the cheaper the robots get.

Same goes for every other factor you listed. All of those things add cost to a business’s bottom line. Where they will inevitably try to claw back some of those losses, are labor costs. “Sorry, but due to overhead constraints, this is the best I can offer you. Take it or leave it”. And in an economy that’s under pressure, people will take whatever they can get.
