The point isn't that there is a 1% of wealthiest people on earth. The point is that its income is a quarter of that of the national income and that it controls 40% of the national wealth.
That's the issue. There'll obviously be a "top one per cent" in everything. There'll a top one per cent of most active members on this board, for instance.
Which is why the issue isn't just an economic one, isn't just "they have more money than us".
