I disagree, as would many men. I don't see how you can think that people choose it as a lifestyle choice rather than one through want.
No, in this century, a planned parenthood is a pure lifestyle choice. Even if we leave alone the "pregnancy as a method to get more rooms and money out of powers that be" scenarios and focus purely on middle and upper class fully planned pregnancies. It is still a lifestyle choice, ie. you get a house, a car, a pet or a kid, or both and you make your life revolve around one or the other for number of years.
In planned scenario most people decide to have kids for no other reason than to complete set up of their nest/house, as an alternative person "to love" in ones life. In case of most families lifestyle choices follow career first, for a decade, then go into "house making" mode in second decade, to which gradually one adds a cat, a labrador, and up to two children. But also, to put it brutally, as a method of repairing the nest. As a reboot of the "love" element in "house" environment after relationship strain following the "career years". This scenario is very pronounced in UK where average age of middle class pre-planned parenthood age goes up with every decade, and now oscillates in late 30ies and early 40ies.
It's no longer "want" as a existential requirement (in the way you "want" and pursue things in life - ie. "I want roof above head and food on my table for my family"), it's "want" in lifestyle sense and in cold hearted clinical terms, it's relatively selfish one - you make a decision to follow that lifestyle, together with accessories to play it - estate cars or 4x4's, nannies and extra space in household dedicated to "it", while relying on the rest of society to maintain the health of, educate and provide your child with a job or purpose in the future at considerable cost of many not being able to afford this lifestyle in their lifetime.
All of the above make me sound like a heatless a-hole, and I hate myself for saying this, but in purely sociological terms, in 21st century, in our lifetime, as the society ages and the costs of maintaining 0-21 age group far outgrows costs of maintaining retired age group (happens already) we will see reverse of all policies surrounding children and encouragement to "have" children. Couples will be financially rewarded for not having one (already happens in some countries). And as soon as free education and financial support for children is revoked, "kid" lifestyle will be replaced with open top sports car and holiday homes as lifestyle choice.
Worst part is, she is now speaking about a 2nd and while I love the little one to bits, I am terrified of having another.
