I'm curious about why you think that earning money professionally, or as a business, is a problem.
Say that I with a couple of friends could, in 9 months or so, develop a system that would, for JC Penneys (say), save $10M or raise their sales by 1% (I think they are between $10B~$15B in annual revenue, so this would be around $100M+ revenue and at 5% margin (for example) worth about $5M to their bottom line...)
I think it would be reasonable to charge them $1M+ for this work.
One might argue (they would argue!) that 3 guys for 9 months should NOT be $1M+ -- that we were being greedy. But, I would argue that we are creating significant positive value after our fees.
Would you agree with their reasoning and disagree with mine? If so, that's fine - but I am curious as to why.
