I don't think that is what is meant. The comment isn't about financial support. It's about poor, disparaging attitude to people who choose to have kids. As though it's a fault.
Nobody complained of little time because of kids. But that assumption was made. It's insulting to suggest I somehow regret having kids due to little time when those kids have become my reason for being. The suggestion I regret my kids for want of hobby time is on one of the biggest insults anyone could make.
That's not to say I believe the comment was malicious or even intended to insult. It's very difficult to understand the huge upheaval in priorities that take over by instinct when you have children unless you've made the decision yourself. For some, it's understandbly too big a sacrifice and that's ok! It is, as you say, a choice.
As an aside, I don't think it's right to boil everything down to financial terms and incentives. If I thought that way, I wouldn't have had one child let alone three. They cost a lot of bloody money.
