I think this is much more of your depression issue than what might happen I n your country years from now. Depression often comes from suppressed anger. You have reasons to be angry at your parents. If you spend some time with good therapists they will walk you through the fact that you cant change the past, only the now and future. Taking some sort of good action, working on Yourself and issues you care about will ease the depression.

I caution feeding the anger. It is easy to find outlets for your anger with like minded people that have been wounded in their own way. I suggest for instance putting energy towards building /preserving German culture rather than attacking other cultures. Not because they may not deserve your scorn, mearly because it will leave you hollow and empty.

You will find good people from every culture and race, and a bunch of fuck twits also. Cultures with more social handicaps are a greater challenge to overcome while trying to become a rational self actualized human being. It's very difficult to stand up against the culture you are raised in, as your ancestors could tell you.

Being closer to your parents age I find that the only real satisfaction comes from the things we grow,make, and build. Children, businesses, art, farming/gardening, building, things such as this. This and it's effect on the people that are touched by your efforts is where the satisfaction and fulfillment lies.

My parents were the WW2 generation. I didn't see any joy or fulfillment from the war, or other political movements such as civil rights. They saw them more as things that had to be dealt with. Their joy came from the types of things I mentioned above.

So my suggestion would be find positive outlets for your angst and watch it turn to determination, and eventually joy.
