Anyone who has taken a good look at the back label or considered taking part in a boycott has figured this out pretty quickly.
Consider this for a moment, all these products are concentrated in the hands of ten corporations, but as near as I can tell, they seem to be in competition with each other. Coca cola and PepsiCo, Nestle and Mars, etc.
Nestle is a Swiss company
There's certainly a good reason why these ten companies might dominate their markets: They're very, very good at what they do.
Having worked extensively with both Procter & Gamble and Frito-Lay (PepsiCo), I can attest to their commitment to product quality/performance and consumer value. They have justifiably earned their position in the marketplace by doing a better job than their competitors.
