Answer:
To be prosperous and independent.
Step-by-step explanation:
An infinitive phrase is a group of words consisting of an infinitive, a modifier or the use of pronouns, direct objects, indirect objects or complements of action or state expressed in the infinitive. Examples include, “to walk,” “to read,” or “to eat.” Infinitives can act as nouns, adjectives, or adverbs. As a noun, they might act as the subject of the sentence. For example, “To travel is the only thing on her mind.” As an adjective, they'll modify a noun.
Pretty sure it's to be prosperous and independent. Hope this helps!
