There are some kinds of nonviolent behavior we don't allow because we (I guess we is majority of society?) think it's wrong, often around issues of financial exploitation. For example, even if you are mentally sound you can't sell yourself into indentured servitude because that tends to only happen when someone with power exploits someone desperate, often (but not always) due to reasons out of their control.
UBI is basically an artificial wage. Like a lot of things in life, a wage is a negotiation between two entities of vastly different levels of power. As every public company proudly proclaims, the value of what employees do for them is far far less then the value the employees receive.
Why do you think those workers accept this fact? They like getting less value than they generated? It's clearly the result of an exploitative power dynamic - one side has to work or not eat, the other does not.
If you think someone should not have medicine and food dangled over their head in work negations, the answer is workers need to be paid in real value of the capital that they create and that needs to law.
I hope one day our wages are looked back on like no minimum wage, the 6 day 14+ hr work day, child labor, indentured servitude, slavery and etc which were often viewed as normal at their time but now disgusting.
This GIF is mocking the idea of UBI and while for sure a silly meme, has an element of truth IMO.
Capitalism works on leveraging advantage to pay workers less than the value that they create. Do you have anything to say about that, or are you going to continue to suggest magic discount coupons (UBI) which are worth less than the value a worker creates are something besides slavery with extra steps?
Feel free to scoff/mock me for questioning sacred holy capitalism - when immoral ideals are questioned and no logical answer is available, history tells us emotion and feelings are the standard responses.
