Is any of that OK? No. It's just not surprising.
What do you mean by "cost"? They both have to pay the same price, one might have to spend less time to make that amount if that's your point, but that's kinda obvious.
Maybe if there were no taxes or utilities, food, housing, etc.
$50-60k in taxes (my take home is about 40% of my salary). $2k/month in rent/mortgage, so about $25k/year. $1k in utilities and food ($12k). So, we are up to $96k and haven't even touched on car payments, clothing, entertainment, etc.
