I was mind blown when i found that this is a major investment thesis in argentina.

That is the opposite of a problem - it emerges because we have tools that make things more efficient than just throwing toiling bodies at it. We had economies which were based upon it, it was called slavery. Capital compounding its gains through better capital is how we get progress. The presense or absense of the capital advantage is part of what separates third world wages from first world.

The industrial era problem isn't capital but that economies of scale encourage consolidation heavily and make running small business an even more uphill battle. There is at least a counterbalancing force of competitive pressure and antitrust to promote some splitting for innovation's sake as opposed to just one big stagnant monopoly winning out just because it is biggest.
