Why does Erna Kranz say, ‘I could only say for myself’? How do you view her opinion?

Erna Kranz’s statement, “I could only say for myself,” reflects her personal perspective and acknowledges that her experience may not be universal. She doesn’t claim to speak for everyone; instead, she shares her individual viewpoint.
She highlights some positive changes in Germany during the 1930s, such as increased salaries and a sense of regained purpose. These factors likely contributed to her favorable view. However, her viewpoint is limited to her own circumstances. As a teenager, she might not have been fully aware of the broader political and social implications. She may not have been directly affected by the persecution of Jews, political repression, or the suppression of dissent. Her experience might not reflect the reality faced by marginalized groups.
