As someone who has a MA and PhD in another field, while I didn't pay for my education (I was paid anywhere from $3,000 to $22,000, but most often around $16,000/year) I forewent 8 years of income to come out making the same as I did with a BA. So I lost 8x$30,000 or $240,000. Therefore, that part of her argument is quite flawed.

I also don't think that renting out love is accurate, at least in my experience. My therapist doesn't just love me for the 100ish minutes we spend together a week. She recently went on a 2-week vacation after a really tough medicine episode for me. She left me with 4 cards to open over that period, she recorded a voicemail on my phone as she was leaving for me to listen to when I missed her, she allowed me to email her and she responded, and she called me when she got back into the country as it'd be 2 more days til we saw each other. She also arranged for me to see a colleague if I struggled and got pre-authorization from my insurance company to do so. She didn't bill for this--it was done out of genuine caring and love that doesn't just disappear once we'll stop seeing each other - doing such things will, but the love and caring not. I have a former therapist, stopped seeing her almost 6 years ago, and we still email a few times a year and I saw her when I was visiting the place she lives/where I used to live and we had a lovely afternoon together. I can affirm that we both still feel a lot of love for each other, and I haven't paid her a dime in nearly 6 years.
