I mean I can understand you having trouble if you have less than 100 furniture objects and aren't versed in how the building system works... Maybe then you would have a gripe about the 'earning' capability. The layout is one of the most profitable original layouts... with additional bushes.

If you're talking about that crappy 'semi-automatic farm' thing that noobs are doing at the castle house with conveyor belts, they are wasting their time working towards repetitive motion disorders... There are much better contraptions to be made in other layouts with the same (or less) castle furniture which you don't have to jam sword 10,000 times in order to operate. Try the tropical island if you want to make something really effective for farming. Better yet, get a respawner.
