Should be a clue.
Right to work is the best and only solution a state and people have in a situation where federal law gives unions an unfair bargaining advantage.
Economically and morally if the playing field was fair, unions can, and did do good. Firms should be able to contract with a union to exclude any non unions workers, as well firms should be able to exclude any union workers. But until the labor market is freed, anyone whining about right to work being people wanting to 'freeload' on unions 'work' are just lying about the situation.
End the NLRA (Wagner Act), RLA, etc etc and then you have a case. Until then your fascist squeals of indignation fall on deaf ears of the people your unions disemploy.
Oh and Read some Hazlitt
