Doing this can only lead to resentment amongst young people, who would feel that they were being used.
Is that the right tense agreement using past progressive - were being used - in the sentence above? It doesn't even look like any conditional form that I used to see, so using past tense makes it quite confounding for me to read. Do you think it's grammatical? If it is, then help me to understand this sentence too.
