Can anyone afford to be a SAHM and still save for retirement

"Cat's In The Cradle" by Harry Chapin 

My child arrived just the other day
He came to the world in the usual way
But there were planes to catch and bills to pay
He learned to walk while I was away
And he was talkin' 'fore I knew it, and as he grew
He'd say "I'm gonna be like you, Dad
You know I'm gonna be like you"

And the cat's in the cradle and the silver spoon
Little boy blue and the man on the moon
When you comin' home, Dad
I don't know when, but we'll get together then
You know we'll have a good time then

My son turned ten just the other day
He said, "Thanks for the ball, Dad, come on let's play
can you teach me to throw", I said "Not today
I got a lot to do", he said, "That's ok
And he walked away but his smile never dimmed
And said, "I'm gonna be like him, yeah
You know I'm gonna be like him"

And the cat's in the cradle and the silver spoon
Little boy blue and the man on the moon
When you comin' home, Dad
I don't know when, but we'll get together then
You know we'll have a good time then

Well, he came from college just the other day
So much like a man I just had to say
"Son, I'm proud of you, can you sit for a while"
He shook his head and said with a smile
"What I'd really like, Dad, is to borrow the car keys
See you later, can I have them please"

And the cat's in the cradle and the silver spoon
Little boy blue and the man on the moon
When you comin' home son
I don't know when, but we'll get together then, Dad
You know we'll have a good time then

I've long since retired, my son's moved away
I called him up just the other day
I said, "I'd like to see you if you don't mind"
He said, "I'd love to, Dad, if I can find the time
You see my new job's a hassle and kids have the flu
But it's sure nice talking to you, Dad
It's been sure nice talking to you"

And as I hung up the phone it occurred to me
He'd grown up just like me
My boy was just like me

And the cat's in the cradle and the silver spoon
Little boy blue and the man in the moon
When you comin' home son
I don't know when, but we'll get together then, Dad
We're gonna have a good time then

This song makes me very sad. My little one is growing up so fast. In a blink of an eye, he can now walk and gesture to bring his point across. My job is great because i get to leave work on time, but it still requires me to be at a certain location from a certain time to a certain time. And by the time i am done fighting the peak hour traffic, i am so so drained. I don't know how other mothers who work long hours does it. I just know i am missing out on parts of my little one's life and it makes me sad. 

sometimes i feel like quitting and just saying i want to be the domesticated goddess - cook, clean and watch my little one grow up. but how does that square in with the reality of living in singapore, a fast paced modern city where inflation increases at an alarming pace and materialism and consumption is at sky high? 

what did our parents do? was it easier or worse back then? i don't think anyone kept late hours then. my days as a kid was predictable. my mum went off before 9 am, my granny would sent me to kindergarten by 10 am and i came home at 12 pm. lunch, nap, day dreaming and then my mum would come back home before 6 pm. dinner, tv and bed. simple. 

now? i think most of us office warriors would consider ourselves lucky to be home before 8pm. 

SAHM? possible?
