This is totally an adult individual leeching / parasitic on another person.

I am having a rental business to make a profit, not to feed parasites and offer housing.

(Sidenote, cattle inventory in the US is at an all-time low and now we are shutting down imports from the south because of a parasite "new world screwworm") - so I guess my steaks are going to go up no matter what. 

However, in such a case, a rescue fund would hold a superior position in the capital structure compared to the common equity investors, including yourselves and there acting as a parasite taking equity upside from all common equity investors.While this might provide a safer position for the pref equity slash rescue fund, it would also significantly impact the returns for common equity investors (previous guys).

I'm all about capitalism, but I don't understand how these parasites sleep at night. 

Given, That Im allergeric to Cats. or that the Center for Diease Control claims 40 million Americas are now infected with the parasite Toxoplosmosis Goni from Cat Feces.

It's obvious you only see them as objects of contempt, parasites on the a** of humanity.
