Do you have any statistics/reasoning that support this argument?
I'd say it's simply because it's a crappy, low-paying, exhausting job with too many working hours, which not many people want. Men usually get such jobs.
Teaching is a low-paying job with too many working hours. Women work at places like Target, Wal Mart, and McDonalds which are not exactly known for how intellectually stimulating and high-paying they are. This is a weak argument. People who are uneducated and/or have life circumstances that force them into low paying crappy jobs are the people who end up with those...women, men, white people, black people, asian people...people in general.
The real question is, though, why don't the women get/take such jobs. I think the answer is a mixture of the following: (1) they are worse at such jobs than men (physically weaker and menstruating, which I assume might matter for a job like truck-driving), (2) (I assume) women get more government help, because they are more often (single) mothers and (3) women can play on other qualities (more social, better caregivers, more attractive, less dangerous) that allows them to get other jobs (nanny, waitress, secretary, ...).
And this power imbalance between workers and employers is terrible. Yeah, all pretty standard socialist stuff I’m a huge fanboy of. It’s of course not only gender roles that play a role here.
You reasons are pretty bullshitty, so I don’t think I ever want to talk to you again. Bye!
