We have the same policies in Norway, with open tax registers. It was made for transparency. But it's a bit flawed, as you can't see things like tax deductions, so the number you see is just a ballpark figure, as much information is hidden. And besides, a lot of entrepreneurs, rich people, etc. will almost guaranteed have a holding company, and get dividends at lower tax rates.
