It's an excuse.
The Republican party used to stand for personal accountability. Now it stands for blaming everyone but themselves.
Look at who is really supporting Trump. None of them support personal responsibility.
I have always thought that conservatives threw around buzzword terms like personal responsibility and rugged individualism too quickly, without ever stopping to really define what they really meant about it and what the consequences were.
