Because you cannot hide the imbalance of disconnecting yourself from the material reality that's involved with making your lifestyle possible by outsourcing to other human beings, over multiple decades, without it coming back to bite you in one form or another.
See the hundreds of thousands of people in US that have died from opioid overdoses. 50% of the US population, specifically those living outside major metro areas, experienced a slow collapse (over decades) that was not unlike the fall of the Soviet Union.
A country should have _some_ semblance of what it is to truly source, manufacture, and produce the lifestyle that's made possible in the country. When the top 15-20% become completely disconnected from the other 80% working menial service jobs because the core manufacturing has been outsourced to outside the country, it will come back to bite you.
"Man must feel the sweat on his own brow" or at least have an appreciation for what makes this possible. Your comment essentially implies that you feel that you are above or should be disconnected from this reality, which is dangerous.
