YOU SAID:
The ambitions of some Americans are limited by failing schools and hidden prejudice and the circumstances of their birth.
INTO JAPANESE
いくつかのアメリカ人の野望は、失敗した学校や隠された偏見とその出生状況によって制限されています。
BACK INTO ENGLISH
Several American ambitions are limited by failed schools and hidden prejudices and their birth situation.
That didn't even make that much sense in English.
