If you're going to host an event in your home, could you please clear off enough space on one of the covered surfaces for the snacks people are bringing, wash the dishes and empty the trash, remove the clothing from the living room so people have a place to sit, vacuum the food debris off the floor, and open a window? Yeah, it's none of my business, and I have the option of never accepting your invite again, but these are life skills you should have learned in your twenties, the latest, and if you're going to blame your life circumstances on "the man", at least try to take care of this one thing you do have control over.
I hardly ever had parties in my bachelor days in an apartment, but when I did, I shoveled all the junk into closets, vacuumed the carpets, and cleaned the kitchen and bathroom with copious amounts of bleach till they sparkled. Neither room had a window or working (read: "ducted to the outside") exhaust fan. When the first batch of friends arrived shortly after I completed the decontamination process, the first comment I heard was: "I feel like I'm being sanitized from the inside out!"
