Technically no, this photographer is putting flowers under a blacklight and photographing them, resulting in a picture of basically what a human would see IRL in that scenario (aside from things like contrast/exposure variances, etc). It's not really the same as what UV sensing animals would see. These photos are of regions of the flower converting UV light into human-visible visible light (via fluorescence, same thing as a blacklight poster). UV sensing animals are seeing actual ultraviolet being reflected by the flower as well as visible light, so it's not the same thing.
That same house in my area costs at least 10 times that amount. I was lucky in that I had "only" $80,000 of debt from my bachelor's, a housing situation via marriage, and a career path with solid pay (after going back for an associate's while working in a low-paying job post-graduation for 7 years). I only finally paid off that debt 2 years ago and I graduated in 2008. I don't know how a lot of people manage.
College graduates (PhD or otherwise) drowning in debt and not being financially able to pay it off is common enough here in the US that it's a trope, and likely the basis for this "joke".
