According to the dictionary, the melting pot theory is “a place where a variety of races, cultures, or individuals assimilate into a cohesive whole.” melting pot can be described as a fusion of nationalities, cultures and ethnicities. It is a mix off the old culture and the new culture. One incorporates good traits from their native culture and incorporate good traits from their new culture to benefit themselves. This is how the melting pot develops.  The “melting pot” metaphor implies both a melting of cultures and intermarriage of
ethnicities, yet cultural assimilation or acculturation can also occur without intermarriage.  Some argue that cultural assimilation is important to the maintenance of national unity, and should be promoted.
