To earthwalker99: You got downvoted to death because you called out downvotes against you, but to explain more issues with your argument: Capitalism is a system of organizing society based on private ownership of the means of economic production. You're saying capitalism is about prioritizing the rights to capital accumulation by the current holders of capital, which is one specific form of capitalism, often called crony capitalism.
Private ownership of the means of production is more orthogonal to workers rights. There are capitalist economics in countries with very strong workers rights and unions, but where the means of production are still privately owned. Capitalism is fully compatible with strong family and medical leave protections, even though those who own the means of production are disincentived in the short term from giving workers rights. The fact that the US is worse on workers rights isn't a problem unique to capitalism.
So called "right to work" laws that actually give employers the right to fire for no cause. As long as an employer doesn't say what the cause was, employers in those states can fire you for "no cause" even if the hidden reason would be an illegal cause if they stated it. It's only illegal if someone gets caught specifically saying the firing was because the employee is having a kid. Coincidences are not considered admissable evidence in those courts.
I think you’re conflating “at will employment” with “right to work”.
The first allows no-reason, no-notice termination of employment by both parties (which doesn’t really work - the employee usually needs income more than the employer needs a single employer).
