What Does a 600% Wealth-to-GDP Ratio Actually Mean?

Recently, I read that US household net worth approaching 600% of GDP. GDP is roughly what the economy produces in a year, while wealth is the accumulated value of assets, so I know they're not directly comparable. But historically, this ratio seems much lower. What does a 600% wealth-to-GDP ratio actually tell us? 1. Are assets massively overvalued? 2. Does it imply future returns will be lower? 3. Are we expecting future growth will be so high, that it will bring down the ratio again? 4. Or is it a sign that modern economies (e.g. AI, Space, Quatum) naturally support higher asset values than in the past? Curious to hear how investors interpret this metric and whether it's useful at all.
