"Full-time employment" is socialist nonsense. De facto there are no "employees", we all provide services to each other. Essentially, at some point the "social engineers" as part of their perpetual crusade of redesigning society decided that it is good idea (for them - because it is e.g. easier to quantify and exercise control) to standardize relationships between individual service providers and service consumers. Just look at this nonsense around Uber going on lately: government agents insist that they get to decide how to classify their drivers, as contractors or as "employees." Absurd.
