That's a fine sounding sentence, but what do you actually mean by that? Do you mean the wealth distribution when subtracting out the equity value of financial businesses? Or ignoring the net worth of individuals who happen to be currently employed in the financial sector? My first reaction is that your comment is suspiciously vague, and might be confusing income with wealth.

Sorry, I was just spitballing. As the article was about both wealth and income, I should've mentioned both. But especially with wealth, I don't know how to remove the financial sector from the calculations, as just fromreading this article, I don't know from what they derived their percentages (and even then this is probably beyond my expertise, not being an economist). Net worth of people in the financial sector is probably a good starting step.

Or more generally, a breakdown of the areas of work of the richest 1 percent of several countries would definitely be interesting (again, both wealth and income).
