The question of gender equality in modern market society

If the traditional family is abhorred like it is in the depicted picture, then perhaps modern free market would be considered as a better place for women to grow or thrive ... What needs to be acknowledged that often women in the modern market society also complain about their unequal treatment (not to mention colossal amount of sexual harassment cases [1] which doesn't seems to reduce with more freedom) like why their wages are not as same as men? Its seems this complain never questions the foundation of free market society which legitimize free competition in a social Darwinian context means the FITTEST WILL SURVIVE/THRIVE [2] ... free unregulated competition eventually create conditions for inequality, which hurt both men and women equally.
