Adult child of an alcoholic here

[no_hypocrisy]

15. TSF's Cabinet of Alcoholics can be traced to his youth and early adulthood.

Both Trump and his father put so much untenable pressure on his eldest brother, the presumptive heir, that Fred Jr. turned to alcohol. And even as a child, DJT saw his opportunity to displace his brother as one day running the family and the family business. No compassion for his brother.

And DJT also witnessed how his brother was essentially helpless at being independent. Little Brother was in charge now.

My theory is Trump doesn't want any Cabinet member to get more attention and credit than he's getting. Simultaneously he's disgusted by their weakness for alcohol and pleased that he can control them. They'd never turn against him.
