For example, if a highly skilled person has to pay a high income just because they earn more with their skills (education background), doesn't it unfair to have a higher tax rate for hardly owned income?
Doesn't this demotivate society?
What is the scientific explanation?
Below is an example from Australian Tax rates.</p>

Very much in agreement with @1mulfon1's points regarding an absence of settled opinion. Many schools of thought diverge on this topic. However, neoclassical economics does identify as a scientific worldview. And it's also such a powerful/hegemonic set of ideas, people now use neoclassical economics in everyday language, never mind policymaking. So, in terms of neoclassical economics, here is the core idea: https://dash.harvard.edu/bitstream/handle/1/12027853/SSRN-id463241.pdf?sequence=1&isAllowed=y

How do you explain to a layman "Why the rich should pay more taxes?".
For example, if a highly skilled person has to pay a high income just because they earn more with their skills (education background), doesn't it unfair to have a higher tax rate for hardly owned income?
Doesn't this demotivate society?

There is no scientific explanation for any sentence that has **should** or **ought**. Such worlds imply normative value judgements. Science, properly done, is value free and hence science itself can never tell you what *should* or *ought* to be done in any situation.

> Doesn't this demotivate society?

Depends what exactly you mean by demotivation. It is well established non-linear income taxes distort peoples optimal labor supply, educational demand choices (e.g. see Hindriks and Myles Intermediate Public Economics Ch 16). This does not always lead to less work being done since negative income effect might cause some people to work more but it does generally lead to loss of welfare of individuals. However, if under prevailing political ideology social weights are put on redistribution, this would be simply viewed as justified cost.
