There are 2 situations, and the 1st one is sadly the current reality:

Situation 1: Europeans are terrorized and murdered by non-Europeans at exuberant rates, Europeans are paying for non-Europeans, non-Europeans are “discriminated” by “racism” and “islamophobia” in Europe, non-European countries remain poor.

What should have happened and what needs to happen:

Situation 2: 99% of non-Europeans go back to their ancestral homelands, they will bring all the billions they have earned in Europe and make their countries better, Europeans will stop being terrorized and murdered by non-Europeans at exuberant rates, billions saved in Europe will go to support the elderly that have built Europe and to young families that are the future.

Do you want a safe and prosperous Europe, a prosperous Africa, Middle East and Asia?

In other words - what is better for Europeans - (a) that non-Europeans do some non-essential work and murder Europeans from time to time, or
(b) that non-Europeans go home, do not do some non-essential work and stop murdering Europeans from time to time.

Should be an easy question to answer.

Very easy to achieve in principle.

Totally possible to achieve in reality.

This needs to stop. The mass murder of grand children of people that fought in WW2 so that their children will never have to die. But here we are. Betrayed. Mass murdered not by Europeans - Germans, but by total outsiders.

Where there is a will, there is a way.
