how could the guys afford so much?

i did some research and the average salary(now) for a theoretical physicist is 58-115k assuming before tax, rent averages at 2-4 thousand add on water bill, electricity, car payment, gas, food all together that’ll add up to probably 50k+ a year, assuming they pay middle ground for rent (3k) that alone adds up to 36,000 per year. let’s assume the guys make 75,000 a year as a middle ground, they then take 18k off for rent (split halfway) that leaves them with 57,000, then take off like 15k (estimated) for food, water, electricity, etc they order takeout every day and buy expensive collectibles and comic-con tickets, how do they afford it?
