>>1404468100% employment among all eligible, healthy, and able-bodied adults is achievable. the only counter-argument I ever hear to this is "what about babies, children, people with cancer, retired people, and seriously disabled people?" They obviously wouldn't have to work or would work in a limited capacity. "100% employment" doesn't mean literally put babies in coal mines. It means make sure that everyone who can work is gainfully employed and not desperately looking for a job. Because that process, looking for a job, is what creates opportunities for capitalists to build up a larger and larger reserve army of labor, since the reserve army of labor is comprised of those proletarians who are desperate for a job and willing to scab, work for less, etc.
Higher employment creates more organizing opportunities. As does lower rates of imprisonment, since, in places like the USA, convict labor is a huge source of driving down domestic wages (along with undocumented migrant labor, documented migrant labor, outsourcing, and automation).
