It doesn't cost me much, honestly.
The clothes argument doesn't hold water, IMO. Few companies are still in full business attire and even then, you buy 2-3 suits and they last years. I wear a varied dress code and would have these items in my closet anyways.
I live in shorts and T-shirts. Just to work as a teachers aid or assistant at my local library I would have to go out and buy all new clothes. So this doesn't apply to everyone. I guess I could work at a car wash with my present attire.
I need the benefits; my employer covers the bulk of my insurance. I pay $10 a month for a pretty decent PPO plan. When my DH was working, we ran the numbers and we'd have to pay $190 a month for him to add me. Not to mention the continued education my employer covers. I am able to stay current in my area and it's not on my dime.
$10 a month! That's fantastic! Most of the two income households I know have one insurance or the other because it is cheaper to add the spouse and children then to have separate insurance. You are very lucky. Again this doesn't apply to everyone.
I also have a good 401K plan set up. My parents divorced after 28 years of marriage. My mother never worked FT anywhere long enough to save for retirement. She will NEVER retire. EVER. The closest she may come is to come move in with me when she's too old to work and we will care for her. I will not make that mistake and assume my DH will take care of me. I know better.
My Dh works for the DOD. The ex-spouses of military and civilian employees of the military are eligible for part of their husband's 401k and retirement based on how long they were married. Pretty sure this is how it works for all Federal government employees. Your mother would have received half of your dad's retirement having been married 28 years.
I know there are other companies were this is the norm because I have divorced great aunts living off their ex's retirements. In any case she should have gotten a better lawyer it sounds like she got screwed. I've known many women in that position though. I've also known women who fought for what was rightfully their's and won. So once again this doesn't apply to everyone.
Gas isn't a big deal, I don't drive far and it's rarely in traffic.
We don't have children but we've run the numbers already and it won't put too much of a dent in our budget if I'm working.
I bring lunch or eat for free at work. It's rare that I eat out. We eat out more when we're stuck at home just so we can get out of the house.
Matter of fact, I'm confident that it would cost us more for me to not work.
