Yes. And it is not my assumption, just statistics. Look it up, it is easy. Your "small percentage" amounts for the 1%-ers to twice as much as all taxpayers pay.

I think that data a bit misleading Slobodan. I looked up the Bloomberg article and then the 2016 data sheet it refers to.
Those earning $100,000 to $500,000 dollars in the US account for over 40% of tax payments.
Not including corporate tax.
The income from the $10,000,000 bracket looks impressive until you factor in what everyone else pays.
Then there is the issue of tax avoidance by the super wealthy, estimated at $200 billion yearly by someone who has number crunched data:

They don't do capital investment. Over the last 20 years I've seen little proper capital investment worldwide, apart from China. And even that may be debt funded, heaven help us.
What I have seen is that the greatest wealth generators for most folks are small business owners. It's the small business owners who provide the most jobs in most nations. They tend to strengthen social networks and give cities more resilience by paying rates and spending and employing locally.
I don't begrudge anyone their material goods, but IMHO you could get rid of the really wealthy and life would go on just as well, but lose sight of your small businesses and the values they represent, and watch your financial system head straight to 1929.
