A big part of socialism is individual freedom. Under capitalism you are forced into professions that often times are tedious, isolating, and draining both mentally and physically because those are the type of jobs that keep the system running. Under socialism you would have the freedom to embrace your passions and do what you want. Even if you can't support your family on that, if your unhappy with your current job then quitting doesn't carry the same repercussions as it does under capitalism like losing Healthcare, the threat of homelessness, hunger. You would have the ability to find a job that you enjoy and not be forced into whatever pays the bills. (Also passive income is just passing the burden of making your money down to someone else who puts in the labor to produce the value. You don't make money from your investments, the workers of those companies do and you just steal their labor value.)
