This is my assessment due to years of experience.
If you say, "The rich should pay their fair share." or, "Everybody should be paid a living wage." and I ask you to give me a specific number and how you arrived at that number, I'm 90% sure that you won't have an answer and I'm 99.9% sure that you won't be able to find two people who use the same rhetoric who would produce the same number for the same reason.
This is a big reason why I follow so many pages with which I disagree and I never unfollow over philosophical or political differences. Eventually, you kinda know what people actually mean when they say something. You get a sense for intentions that people won't say out loud yet.
The closest thing to activists giving us a number is "Fight for $15." But, spend two minutes talking to these people. They all want the minimum wage to be higher than $15 - some want it to be much higher.
This is important because the people who fight for $15 are the same people who use the "living wage" rhetoric. Of course the fight for $15 people don't agree that that's really the wage - the $15 number got pulled out of somebody's ass and became a meme. It's patently absurd to try to define a living wage, given any standards, at a national level in this country. It's absurd to even do it at a state-wide level. There are places in this country where you can be living in a house with two cars on $15 an hour and other places where you'd barely able to afford to live in a closet. I was spending more on a one bedroom condo in DC than my sister was spending on a three bedroom house in Arizona. A living wage in Manhattan is different from a living wage in Hazard County.
That's assuming the same metrics.
But, people don't agree on the metrics. Just over the last few years, the memes about the minimum wage not being livable have moved from not being able to afford a two bedroom apartment (again, state-wide averages) with only 35% of income spent on rent to the same being said with the percentage being reduced to 25.
Why does a living wage require the ability to single-handedly rent a two bedroom apartment? I would say that a living wage is a wage that I can live on (I know, I'm insane). I've lived on far less than $15 an hour. I was making $13.34 an hour when I first moved to DC. So, when you say, "living wage" and pull another round number like $15 or $20 out, I know that it's coming out of your ass and I don't have to respect your opinion.
Fair share of taxes? Again, you're assuming a sharing of principles that doesn't exist. To me, everybody's fair share is zero. Again, I'm in the minority; but, even if I were to agree that our organized murder, pillage, and rape machine that we call "government" has a right to steal some of our money, I still wouldn't think that rich people should pay a higher percentage than anyone else.
But again, give me a number. You probably won't. You definitely won't agree with anybody who uses the same rhetoric. There's a reason. This isn't about equality and this isn't about fairness - you just don't like rich people. Using the word "fair" without giving us a number just allows you to engage in a perverse "If You Give a Mouse a Cookie" exercise in which you're the mouse. We could raise the top rate to 80% and you'd still be complaining that it's unfair. You know how I know? Well again, you refuse to give us a number with a clear reason why you arrived at that number; but, also, before Sweden's economic collapse under a Democratic Socialist economy, the top income earners were paying more than 100% in taxes some years.
This is just an exercise in using rhetoric to disguise lack of nuance. "If I say that I'm anti-fascist and you disagree with my other beliefs and how I conduct myself, you're clearly pro-fascist." "If I say that this will save the world and you disagree with me, you want to kill the world." It's all the same lazy, vacuous shit.
