In a practically-ideal world, everyone would be able to afford the necessities of life based on the time and energies they have been dedicating to work. It is unfair that a worker who is even willing to work overtime, will not be able to afford the minimal requirements for living, while those who work far less than them, will.
The problem with capitalism is that it creates a huge gap between those who know how to make a fortune and those who have dedicated most of their lives to work, just to sustain either themselves and their families. There are also those who have a harder time making money due to their disabilities, seen or unseen, which leaves them no option but to apply for social security, and will not necessarily find themselves being able to do more than that.
With the rise of A.I. as far more competent and cost-effective workforce than us humans, a new social class shall be created out of circumstance — the financially-unnecessary people, those who have better replacements for, theoratically, every job they can or are able to do. Additionally, this class might even be increased in size as A.I. will be able to replace more and more jobs that were once considered exclusive to humans. This includes art, medicine and so forth, and not only basic, more menial jobs.
This would lead to the inevitability of creating a universal basic income for any human being whose competence as a worker is far inferior from his machine/robotic counterpart. It is inevitable because if people will not have any money to sustain themselves, riots and insurgencies might happen across the globe, leading to the inevitability of all unemployed to live off government money, at least of just having a living wage and no more, for the rest of our job-replaced lives.
This leads to the conclusion that we should prepare both financially and mentally to the possibility that we won't enjoy the expanses we are currently available to afford, thus the importance of giving up of some of our financial freedom.
Perhaps eventually, most if not all jobs will be replaced by a more revenue-generating A.I, leading to the conclusion that while it is considered inferior to us, perhaps it will emerge and become a new socio-economic class, leading to inequality between man and machine.
Regardless, the equality of the law and of opportunities should not be exclusive but universal. Those who born with one or more certain disadvantages should be supported to recieve the same rights as everyone else, even in a world where an universal basic income will be humanity's prime source of income.
There should also be a consideration of something else — if we wish to promote and advance humanity's achievements, there should also be funding to education and to any other program that shall improve the quality of the human material. It is unfair, for example, that Africa, the world's second biggest continent, still remains in the shadows of civilization. Much of the African population, I believe, can be of great contribution to many fields if only there would be more opportunities for them; opportunities that we Westerners may take for granted.
Once a basic universal income is provided, we then have the freedom to do anything we like instead of finding ourselves doing jobs we either don't like or even despise. I myself as an autistic man earn mostly money from the government due to welfare, and if I did not have this money I'm so thankful for, I wouldn't be able to be a productive philosopher. Just imagine the opportunities, once A.I. might replace most of our jobs, thus ending the race for the next monthly paycheck
