My guess is that most HN'ers are 1%'ers. Those who are not are on the way to get there. The 1% is not really special and doesn't take much money/effort to get there. The 0.1% would be more interesting.
The minimum income to be in the 1% in the United States is $421,926. That seems highly optimistic to say that most HN'ers are in that category or ever will be.
You might not in the top 1% of devs but probably in the top 1% of your country. Also by being near Amsterdam you are already in the top 1% of the world.
