Back again with Kundera...

I am now currently reading The Farewell Waktz. Already knowing the style, aesthetics, and personality of Kundera, I think it would be quite obvious to make an introduction to this author, so I would rather go to the core of this thread. Please, take a seat, bring with you coffee (or tea), and you are welcome to share your thoughts here.
 
A) The plot takes place in a spa resort. Women and men go there with the aim of improving their fertility. The spa is managed by doctors and psychologists. The rest of the workers live near the spa in a building called 'Marx.'
 
B) Not always, but often, a group of old people with red sleeves do things for keeping the 'order' in both the spa and the neighbourhood of the workers. 
 
C) There are three intellectual neighbours discussing different topics, until the natality pops up. One of them, states: I would not like to be a father, but I am fond of children. I can even imagine this republic (Czech) where the folks decide to pet dogs rather than raising children.
Another also answers: I think having a child is important. It is like you have faith in people. I would not like to have kids if I don't have belief in people. 
And, then, the third friend states: But would you like to keep continuing procreation from a Christian perspective or a Marxist view to protect the proletariat accordingly to our era?

After debating, one of them, takes his dog out to the park and the old people from B) paragraph approached him with the aim of taking his dog. The only argument is that a dog pees in the park and could be dangerous around children. 
Our intellectual hero fought against the old folks, avoided having his dog taken.

When he returned home, he said to his friends: 'Politics stink. In old times, they accused intellectuals who liked to read, and now they proceed against the ones who would rather pet a dog to have children'

Thoughts?

Is it contradictory to work in a spa for improving the fertility of people and then consider that it is better to have a dog than a kid?

I think many topics can be discussed here, but I love that he nailed that (at least in Euorpe) most of the homes have pets and not children.
