Google, whatever its advantages, cannot make one an expert in the history and sociology of the 1950s. The picture you have painted of life during that period is a caricature, one cliche after another, most of it drawn from the fevered imaginations of the feminist movement.
For instance, there were definitely no laws protecting women from discrimination in the workplace. These were part of the Civil Rights Act which was enacted in 1965.
Have you considered that there were no federal laws "protecting women from discrimination in the workplace" before 1965 because there was no need for them? Indeed, one could question the need (and the constitutionality) of such laws even today.
The 1950s represented a major step back for women who had made strides in the three decades before (i.e. winning the right to vote, working outside the home during the Depression and WWII).
A step backwards? Why—because you say so? It seems more than a little arrogant of you to denigrate the choices freely made by women who lived during a time you little understand.
Well, there were also no laws protecting people from discrimination based on race before the Civil Rights Act, and I'd suspect that most people would agree that those laws were needed.
