I would agree with you but this is not the situation we're talking about there. The OP is totally comfortable living with 50% of the income; clearly he's not counting pennies when he goes out to get lunch, and I assumed that's not a situation he's looking to get himself into either (but if he is for some reason, then OK, you're right). It very much seemed like he'd be still living pretty darn comfortably and getting everything he wants at 50% pay. Unless you like to spend money just for the hell of it, I don't see why you'd spend more on your lunch just because you're making more money, when you're already eating whatever you want anyway. > when you get your child, the extra time that you have if you work less will be spend between you, your child/family, your alone time ( if you value it, will be not even close to 50% ) and because having a family is way more expensive, all the money you saved when working 100% and supposed to save 50% would be spend 3 times faster then when you where alone, and then you would have to go back to work. I was thinking more like, invest the money in something instead of directly spending (say) 10 years' worth of 2x salary in like 3 years of daily life expenses. Maybe even use it to start your own business and dictate your own hours... so many possibilities I can't even think of when you have the money.
