Jonathan Guzman and Mayra Finol earn about $130,000 a year, combined, in technology jobs. Though that is more than double the median, debt from their years at St. John’s University in New York has been hard to overcome. The two 28-year-olds in West Hartford, Conn., have about $51,000 in student debt, plus $18,000 in auto loans and $50,000 across eight credit cards. Adding financial pressure are a baby daughter and a mortgage of around $270,000.
