This might sound a little tinfoily, but maybe their hasty kitchen remodel is to burn as much money as possible? To estimate themselves poor (as we say in Germany)?
I also looked into their patreon. The fluctuation of supporters is pretty high. It might be due to the imminent election (I don't give a shit whom you support, but times of uncertainty make people reconsider financial output), but the rate is still above average.
The individual tiers are impossible to identify (at least without being a patron). The special Facebook group "Abbies Angels" (barf) for the tier of the same name has 214 members as of today, but I doubt that the percentage of supporters is that high. Either Assa (who is the admin) goes on a deleting spree every few months or it is all existing supporters in that tier ever.
I am lazy, so lets pretend that they have an equal number of supprters in every tier (lol, no), which is roughly 116 patrons per level (based on today's number). Which would mean that Asshat's level makes 232$ a month, Pricpigs makes 580, Hogwheel's equals 1160 and #autismprincess brings in a whopping 2900. All together =4872$ a month. Most likely on Asshats name.
Should the 214 facebook group members be actual patrons, Abbies level alone would make 5350, plus a bit of pocket money from the others. the lowest would be 463 low tier patrons, so 926$. The last one is the absolute lowest possibility. I think the truth should be around 1800$-2800$. And that is just one source of income. I don't know how much is on Pigs name, but it is absolutely clear that everything called "FatheringAutism" is Ass and Ass alone.
