> Nothing you said in this post addresses why margins need to be a relative percentage instead of an absolute amount 1. nothing you said here refutes anything I did say. 2. you made no case for margins that would be independent of costs 3. I did make a case for why at least a portion of margins would would be relative to costs, which would make margins relative to costs. 4. also I did mention equity which means I did go beyond credit, and equity rates of return vs credit rates of return are the same math, it's just the discussion of financial risk that I left out because it is a complex subject also I added an addendum based on your criticism. You should say how you think this should work so people can learn from you.
