How could it not be a causal benefit?
India and China from their perspective have been on-shore beneficiaries of Western off-shoring for decades, and look at the explosion of growth and innovation they have raked in as a result.
Off-shoring utterly fails to look at value "as a whole" in favor of price. Over time native value AND price tanks while off-shore prices soar because their value increases.
