Farming is industrialising too, and farmers are increasingly de facto employees of their customers - dairies/grain wholesalers/retail multiples.  The whole business of subcontracting work to nominally independent self-employeed contractors is all about avoiding the legal and other obligations that socialists have established for the employer/employee relationship.

Arguably, the small self-employed operators are victims of classical Marxist "false consciousness" syndrome.  They think they are capitalists/independent and even small employers, when in reality they are more under the thumb of agribusiness than direct employees are.
