A lot of jobs formed in the last fifty years are literally bullshit, though. This is a trend that has only accelerated as the globalised Professional Managerial Class proliferate.
On the other end of the spectrum, women were doing jobs that were not considered as economic activity such as child rearing, caring, cleaning etc. These have now been brought in and monetised, though we still have people today who do things like full time caring for sick relatives who are being neglected for providing a necessary service.
Whether the participants of this survey believe in what I typed above or not is probably academic. There are arguments to be made for both sides, though overall women entering the workforce allowing for better equality and economic growth, though so does allowing high immigration which also has more nuances critiques worth looking into.
It is more than likely a case of finding a reason to justify an ideology.
But, as I said before, there are only a finite number of roles in the workplace, not quite sure where Zilla1 got the impression there isn’t. A rudimentary look at the labour market will show this, and a good chunk of the jobs today are duplication or likely to be automated if invested in.
What would be better is to realise Keynes’ vision of people having a job and the hours worked per worker being far smaller, but still receiving a living wage. Instead, women entered and, as with men, ended up working longer hours, having less time for family and child raising, and needing more income to support what smaller families they did have.
