Yes, 5 is enough to see what happens
Again, there are only two countries making more money and with lower unemployment: Norway and Switzerland. And if you're considering just median income (to account for income inequality), there's just Norway. I hope you aren't under the impression that those countries' populations or economies (both with a population less than NYC, and dominated by oil or banking, respectively) generalize to the US.
Ten years ago, I walked into a McDonalds in Zurich. The cost of an extra value meal was (in USD equivalent) about $12 dollars. As a poor grad student, I couldn't afford it. I suspect its more expensive now. (One source puts the cost of a Big Mac in Switzerland at about $7.50; again, that's without the fries and a drink.). The well-off Swiss population can afford such things. To the average working class American, a price increase of that magnitude would make a McDonalds meal a rare luxury. (Especially if that person has kids, who don't earn any wage, minimum or not.)
You can argue all you want that if we just raised the minimum wage, had universal health care, guaranteed a universal basic income, etc., etc. that it would raise everyone's standard of living at some point in the future such that we eventually become like the Swiss and the Norwegians. But please don't pretend that the price increases that are the natural result of raising costs (of which wages are one of the largest for restaurants), to say nothing of the lost jobs that are now too expensive, wouldn't have a real and negative impact on the lives of poor people right now -- even if that negative impact isn't so bad as "the end of the world."
