excellent post dear friend @doitvoluntarily, a very interesting and topical topic.
In general, people of lower middle class tend to be better than upper class people, that is due to the condition of the people, a young lower middle class does not have as many opportunities in life as a young high class , for that reason all the lower classes we try much more to have a wide knowledge and gain a place in society, of course there are exceptions.
Excellent job dear friend, muichas thanks for sharing this information
I wish you a great day
