To someone broke; €1000 is invaluable.

To a millionaire; €1000 is another drop in the bucket.

The first €1000 is so much more valuable than the 1000th. A flat rate across all earnings isn't fair to the vast majority of those who can barely, or cannot make ends meet.

The wealth gap is already growing, if anything millionaires aren't being taxed enough. Singular persons do not need to have enough wealth to begin a small nation, I thought we left such fiefdoms behind with the middle ages.
