Financial/Investment ? for Dialogue Joke

In my story a yuppie doctor walks by a "Tent City" that a community of squatters have built in a park. He makes an ironic joke like "I bet their property taxes don't eat into their investment capital/stock market funds"... (something like that)... meaning that they obviously don't pay any taxes and don't have the means to invest in the stock market or any other investments.

I'm trying to find the right financial terminology for the underlined section to make the right snappy and funny remark.

Any suggestions for terminology and turn of phrase?

Thanks!

Hello.

Just want to set your expectation low: I don’t really see the snappy humor here; sorry. But I’m a humorless person, and am glad to try. FWIW:

The first term that came to mind was “401k” for your underlined text.

Possibly:

“I’d guess their investment manager works on flat-fee.”
“I wonder if they have association dues.”
“My brokerage is EF Hutton, and they lobby for lower property taxes.”
“OB premiums or margin-call?”
“It’s all the A-M-T.”

I, I feel like I’m writing for the New Yorker.

Thanks for the suggestions, OtherSteve.

It's just an offhand comment that the yuppie makes, but I don't know the appropriate financial lingo.

Thanks again for the suggestions. I'm mulling them over and trying to rework my dialogue.

Anyone else have any ideas?
