Well...its because they are. I know of very few one-income-man-is-the breadwinner households. A 2-income household seems to be the norm these days. Of course...most people immerse themselves in credit to buy incessant BS and have student loans to pay off that "degree" they'll never use these days too. Even with 2 incomes...alot of people are dumb, selfish and wasteful when it comes to finances.(luckily I'm the sole breadwinner in my family and if we can't pay cash for something..we don't get it) Furthermore...the overall absense of respect, tact, integrity, common courtesy and common sense in society today adds to the fact that the American standard of living has been greatly reduced from the previous generation.
I may get flamed for this...but...the whole womens-lib-career woman having to go to work and be like a man mindset,(instead of being a mother to her children) along with little-boy, wanna-be men who can't handle marriage, commitment and responsibility has ruined this countrys standard of living more than anything.
No flames from here! Spot on!
If a woman wants to work fine, but she should not give up her womanhood (or femininity) for feminism!
