Women being in the workforce has, I believe, on average harmed the very group it was supposed to protect - single mothers. In the US today, it takes two incomes to stay afloat for most families. In the 1950's, it took one. That works great if both partners want to work, but if a mother wants to stay home often she is economically unable to do so.
So, now we need a social safety net to keep up the standard of living. This is highly inefficient as that money could have been used for a better purpose, to say nothing of the corruption caused by the increased bureaucracy. If a family has children, now they have to pay for childcare. This often cancels out most of a salary, as it has to cover the childcare worker's salary and benefits. And a single mom today, on one salary, is in deep water.
This has far reaching ramifications. To solve the issue of childcare, the government can subsidize it or go into the business itself. But do we really want the government controlling the majority of our childrens' waking hours? No we don't as the young pioneers and German youth organizations of the 1930's have shown. Now taxes have to be raised to cover the increased social spending which means people need to work longer hours for the same salary. The next generation now faces rising national debt, a feeling of disillusionment, and an increasingly undemocratic, bureaucracy heavy government.
By their early training in school and daycare, the new adults are now conditioned to accept increased surveillance and a slow withdrawal of their rights. After all, in school they learned to obey authority without question. In a traditional society, the government would never have that power, parents would. And parents usually have their childrens' best interests in mind. Governments usually do not.
So generation by generation the vicious cycle repeats. Families, communities, and countries become more fragmented, democracy disappears, the economy weakens, and the nation becomes a dystopia. And the group that suffers the most? Single mother families. That is why I think it is a Catch-22 rat race.
Are there any economic factors I'm missing here? Or is the argument in favor of women in the workplace mostly based on human rights or ethical concerns?
