If I want kids in the future, should I start starting dating guys that are career driven?

I’m making 70k as a 27 year old single woman and am located in Waltham. I am a medical lab professional at a major hospital located in Boston. Everybody says that you need to have a dual income of at least 200k to not live paycheck to paycheck if you live near Boston and have more than one kid. I want a family eventually. So in order for me to afford kids in the future, it appears that I would need to reach a 100k salary and also have a husband with a 100k salary so we will have 200k combined. I get bonuses every year but I will also eventually get a job at another hospital that pays better. I used to not care how much the guys I date make (my last boyfriend worked in Whole Foods) but it appears I need to start caring if I want to afford to have kids in the future.
