lets say he spends 20k a year, and actually grosses 30k
cutting his spending in half would leave him with a 10k increase in extra money. doubling his income would be a 30k increase
so if he cuts his spending in half, he could reach the same place if he made only 10k more a year, much more doable
who can cut their spending in half? house payment alone can suck up most of that income
