Land purchase through a bidding process - What is the final price?

I agree with you, the problem is only: How can the gap be changed? In my opinion, it is only possible if work pays off, i.e., everyone who goes to work instead of receiving Hartz IV must experience added value. But that only works for those who can work, meaning those who are physically and mentally healthy and if there are corresponding jobs available. However, that is not always the case, or the jobs are so poorly paid that it simply doesn't pay off to work. So, do you want to lower the Hartz IV rate? Hardly; what about those who really cannot (any longer) work? Increasing the minimum wage so that even more companies relocate production? I also have no patent solution for this, but it must be a fact that capital is taxed too little and labor too much. The lack of educational mobility in Germany is already criticized (children from disadvantaged social backgrounds hardly manage to achieve a high educational level) or the lack of mobility to reach high salaries; it is even more difficult to go from employee to private investor and to accumulate so much capital that subsequent generations benefit from it. Those who have crossed the break-even point (or inherited it) become richer and richer instead. The gap is widening... And how many rich people want to change that?

Nobody here has spoken of great rich people and lazy poor people. That is just a rhetorical trick to discredit my opinion with black-and-white painting. You can save yourself that.

Almost every rich person, except heirs, has built their wealth through hard work, smart investments, and a bit of luck.

why the "rich" should pay again.

I also believe that work must pay off.

If you mean me: Of course, I do NOT want to discredit you!
Still, I often hear and read that people think Hartz4 recipients have to be carried along or co-financed, etc., and that’s also why I didn’t find the stigmatizing label for people as "Aufstocker" exactly appropriate; that much should be allowed to be said.
Do you really believe that I’m looking for tricks to convince you or anyone else of something?

I wouldn’t dare to make such an assessment, neither one way nor the other. What is certain is that there are scammers as well as honorable people; that doesn’t necessarily have anything to do with money. I don’t care how they made their capital. I also don’t exclude "inheritance" because that’s nothing reprehensible either.

...I don’t know where I wrote that. Still, it would at least be possible for them, and the really "rich" people in this world partly do it or see their wealth as a social obligation to help the weaker ones.

Right.....FOR EVERYONE!

You can be sure that I certainly could not have meant you with the "rich"; I rather mean someone who is not active in the house-building forum and, fortunately, there are those who do not only see profit maximization as a goal but also recognize their social obligation.
And... I feel the same way as you, that I have no solution. I just observe an increasingly deep separation of parts of society that I already know from elsewhere. I don’t exclude myself from this, that’s why discussions like these might be useful so that everyone, including me, thinks about it and does not stubbornly cling to their own opinion.

If redistribution has to happen, then it inevitably has to be from us.
