Given that the median home price is over $1 million if you want to own a home you're going to be paying closer to $4k/month for a mortgage. After taxes that 125k is closer to 90k take home and once you put away more of that for retirement/savings you're looking at only $2k/month to pay all the bills and pay for food. For a single 22 year old it's no problem, but for someone trying to raise a family and support others it will be scraping by.
