BS. Let's assume with both making 6 figures, they are clearing $12k a month (rough estimate, depends on state, etc - that and "6 figures" is very broad, so I am estimating from the low end, i.e. $200k per year, pre-tax). The student loan payments with 12% interest (as quoted in the article) would be around $2.9k a month over a 10 year term, or $2.3k a month over a 14.5 years. If they cannot live off $9k a month, they are mind-numbingly stupid.
They probably own $120,000 of brand new car, go out to eat at lunch and supper every day, pay a huge rent on some place that builds no equity and gives no mortgage deductions. Among other things.
