Answer:
Miguel says she only knows how to give orders to servants.
Explanation:
This seems the most logical, and I say this with somewhat confidence as I have read Esperanza before. It makes sense because previously, I believe, Esperanza's house had burnt down, and now she must be accustomed to working rather than ordering because she lost everything to the fire. So, in that way, Miguel telling Esperanza that proves that she must change or things will not fare well for her.
Hope this helped somewhat :)
