I should give an example of how I'd reframe a feminist argument away from identity. The line goes, with either the earnings gap or the wage gap arguments, that women earn less than men and need to be compensated more. My suggestion would be to not argue that women need to earn the same as men. It would be to argue that everyone is being paid a pittance compared to their productivity, and that the root cause of this problem is the exploitative relationship between the employer and the employee. This follows further, while an employee is exploited, they must exploit their spouse to do housework and child rearing (worth $100k per year on the free market) since they don't have the time or energy to do it themselves. Their employer owns the majority of their time and most of what they create. This goes further now, with both parents working it has become necessary for more families to start relying on their children for extra income. The wealth of a few grows and raiding of treasuries all over the world continues. It's just a problem for women, even if we can make a pretty good case it hits us harder.
I'd give you full Marx for that assessment.
