&gt; You have a lot of posts on this topic and do not seem to have something resembling even a remote understanding of the topic.<p>So I can&#x27;t ask? :) Some people here seem to know and I&#x27;m interested so I ask? Weird remark as if the number of posts should indicate deep knowledge.<p>&gt; If my business grows, chances are some business-related expenses grow along with it. How is this any different?<p>Along with it? There definitely are businesses that grow linear with their revenue but this seems not to be one of them.
