Superficial image

Apparently, even in this 21st century, a senior told me that good looks will take you far. It is sad that I cannot be promoted based on my abilities, but was asked to do braces. My teeth is what my parents gave me. Does that mean I should go for plastic surgery too? Or is braces so common such that it has become a must? What about those who cannot afford it? They have no power to choose. Will they be discriminated against?
