I already considered, when I read this thread and came across your first post, whether I should respond to you or generally classify you under the term "forum troll." Your subsequent posts made me lean more towards the latter. However, you have put forward a thesis here that I would like to comment on.
I trust no one... no dealer, no builder, no banker, because they are all humans and make mistakes... or it is simply intended to fool fellow human beings
HEALTHY skepticism is certainly appropriate. On the other hand, with this general attitude you forgo the chance that things might possibly work out better/easier with help. If you pursue this principle of mistrust also in your personal environment (i.e., outside the internet), you also miss out on new, interesting interpersonal contacts (possibly even neighborhood help).
what do you think at what income a man spends his leisure time here? 1 million or 1500-5000 net... I think from 7-8K net a man is no longer here!?
How much someone earns here or not is relatively unimportant. Everyone who posts here in the forum has questions they cannot answer themselves and hopes for help or gladly tries to help others. They cannot answer these questions themselves—regardless of whether they earn 1,500 or 8,000.
Of course, someone with a higher income can also seek professional help—if they want to. However, they might still not be able to assess how well that person works or not. (which brings us back to healthy skepticism) So even those with higher incomes try to acquire additional knowledge. They might just want to know whether their (bad) feeling is justified or not.
I have now been in the forum for about three years. In the beginning—in the planning phase and during the construction phase—I was helped with various questions. Now, it is generally the case that I try to "give back" some of the help. You may think this attitude is stupid and rather have the attitude "I take what is useful and then go my own way"—but that is just how I am.
Mutual give and take.
That’s my two cents.
