The money answer: over a period of 10 years, your wife would be able to earn much more than the $180k in student loans on the outside at market rates. Amortized over the 10 years (which you would not have to do, of course) at 6% interest, would be payments of just under $2k a month. So, that's worth $24k / year, for comparison purposes.
But, you will certainly have more than a median household income, so you should have no troubles with finances, relatively speaking. And you say this is what she wants to do, and where she wants to do it. That is not easy to come by. Places might pay high to compensate for other issues: HCOL, or stressful / poor work culture. They pay high, because they have to.
Despite the impression that benefits like a pension and loan forgiveness try to imply, this isn't a lifetime decision. Let her pursue happiness and fulfillment, and know you have a clock running on the bennies. Make a date for 10 years' time, on the cusp of the loans being forgiven, and the pension vesting, and give her some space for reflection: stay that current course, or choose a new direction? 10 years may seem like forever, but it will come in a blink of the eye.
And if she approaches you earlier than that, then something is off, and it could be time to go then. Nothing in life is certain, but from your description, it seems like this is worth the bet.
