Same here. Despite having intentions of not improving lifestyle with income (so I could be FIRE), it happened anyway with kids. I love my kids (of course) but they are so much more expensive than I ever could have imagined. Cost of living has just skyrocketed in the past 6 or 7 years (cue the 11 year old saying "Siiiiiixxxxx Seeeevvvvvennnn") and wages haven't changed much. Unless something radically changes, I'm chained to this desk for at least then next 10 years.
Oh man, that's so me at this stage of my life. But I cannot easily get out of the rat race, with family responsibilities and mortgages and all...
