> In, for example, the Netherlands the richest people pay less tax [0]. Do you think this is not the case in many other countries?
That's a non sequitur from the previous point. However, on the "who pays taxes?" point, that article is careful to only talk about income tax in absolute terms, and indirect taxes in relative terms. It doesn't appear to be trying to make an objective analysis.
> Is that a benefit of having rich people?
I don't share the assumption that people should only exist if they're a benefit.
> If companies were employee-owned that tax would still be paid.
Some companies are employee-owned, but you have to think how that works for every type of business. Assuming that it's easy to make a business, and the hard bit is the ownership structure is a mistake.
