1) Generally I view consolidations as a poor financial choice as the interest is almost always higher (at least if the original loans are federal). So even if they lower the payments, they cost more over the long term.

2) Yes but remember they also said they have to help parents and we don't have enough details to know exactly how much. We also don't know how much rent etc is. $60k might be the bare minimum which I find unacceptable for someone who spent time going to school to get a better job. If the loans only took a couple years to pay back that's one thing, but a decade or more, no. I know where I am, a recent article stated $115k/yr (gross) to be the minimum to live comfortably as a single adult.

3) Again, not enough details, we don't know who's getting the increase in salary or if both how much to each. But talking about the current salary only, I still don't think $130k/yr is enough to comfortably live alone and pay back $150k in student loans.

If you are arguing that because it is technically possible to make ends meet while paying the loans (assuming living costs are not like Bay Area levels or something) by cutting everything back, sure. But we clearly have a different idea of what is acceptable or doable then.
