There was nothing confusing about what Yamon said , he's a complete drooling moron. I don't even know why you're talking like he laid down some brilliant analysis, kid got rekt and ran off like a little baby but not before grasping at last ditch effort to spew reactionary buzz words like "safe space", in regards to a public forum mind you.
Your "minimum wage based on economics" horseshit is the basic narrative of the capitalist class. It's largely propaganda. You're talking about automation replacing workers (which has already been happening forever) as if it wasn't going to happen anyways regardless of what the minimum wage is. It's in the capitalists' interests to accumulate as much profit as possible. If a capitalist can replace a worker with a machine that would make him more money and give him more convenience, even if that worker only earns 7 dollars an hour, it'll happen, and has happened.
