"...we won't have any idea, only opinions built solely out of sentiment."

You speak for yourself. As a market research manager in the 1980s, and as an experimental biologist in the 2000s, I learned how to understand data. Throughout that time I maintained successful investments and it is my personal experience that has allowed me to comment cogently and informedly on these matters.

I am not ideologically wed to some dogma, but an iconoclast that speaks from experience. Successful investors with decades of experience do have basis for informed opinions, unlike your textual diarrhea.
