jbog, do you want to invest based on what happened in the past few years or based on what is expected to happen in the next few years?
Setting aside the rhetorical question above, each of the cases you presented in your previous post has a unique explanation for the recent sales trajectory. (E.g. MON no longer sells large quantities of Roundup because it went off-patent.) I could elaborate at length on these reasons; however, doing so wouldn’t prove or disprove your contention that sales growth in emerging markets must necessarily come from a diminution of sales in developed markets.
That worldwide sales of multinational companies constitute a zero-sum game and that net growth is thereby unattainable appears to be something you take as an article of faith.
