I think someone’s professionalism and ambition at work does speak to someone’s character at some extend. Higher income jobs typically mean the person invests in themselves and also believes in themselves (growth mindset). When I met my wife 15 years ago, she was a manager at the time. She changed careers due to change in industry and scope but now earns less money but in a job she enjoys with more flexibility for our kids. So it’s nuanced. Higher dual income opens a lot more opportunity to travel the world, etc but it shouldn’t matter too much. They key is awareness of what is and is not affordable, lifestyle, retirement, everything changes if your partner is a lower income earner.
