For all of human history, people have desperately scrambled to assign meaning to their lives. Unfortunately, many people today are living the default white collar office job life, with not that much extra time or energy for fulfillment outside of that job. Because of their inability to escape their circumstances, people find meaning wherever they go.
In the mainstream, most people are working these jobs to support the AMERICAN DREAM pastimes (attempting to buy property that appreciates in value while simultaneously raising kids and saving for retirement). They have the house and kids because that's what success looks like to them; they inherited that cultural vision. To support their version of success, they often must work a job that is not they dreamed. These people take pride in things like their salary, benefits (like health insurance), and stability of employment. Do you hear many people speaking convincingly about how their job allows them to follow their passion or is fulfilling? It is an odd comment to hear. For these people, their meaning in life is to occupy a soul-sucking job for the good of their family. The more demanding the job, the bigger the sacrifice, and the more virtuous they feel. People are very comfortable thinking this way, even when their kids desperately tell them they don't see them enough. "you don't get it kid - you will once you grow up [having internalized this soul-sucking vision of life's purpose]"
So what if you take away that thing that they've decided is their life's purpose? People like this are often so ego-driven, that accepting an income from the government might challenge their whole meaning in life. Rather than dreaming of a new way of life that might emerge for themselves, these people resent the prospective loss of their stunted "life's purpose". What's worse, it's the government coming in, kicking down the door, and cuckolding (you by taking "YOUR" job of providing for your family). People want to feel like "grown-ups", and there are arbitrary parts of that life role that people really settle into.
If someone indoctrinated by this worldview reads this, they will likely respond to reinforce their worldview. They will pick apart how unreasonable I am being, how I am questioning the very fabric of the way we've arranged our society. That is exactly true. I'm not faulting them for living this way - it is the default setting in their culture. I'm not saying they are wrong. I am saying there is much more, and we this worldview is just ONE out of a myriad of options for defining how to live.
