You don't get to choose your country and nationality at birth. But the country you are born in, fortunately, or unfortunately, can affect your entire life thanks to its social position as well as other factors. Each of these is highly important for an individual and help shape their personality and undoubtedly, the citizen of every country has the right to get the best access to these and attain progress. This is known as social mobility, let's investigate and elaborate it further.
Basically, social mobility is the tendency of an individual to progress or decline in the position they are currently in. This 'position' actually refers to the class system, which you can imagine in the form a pyramid- the lowermost portion being the lower class, the middle portion being the middle class and the uppermost portion known as the upper class. You can also think of an upper-middle-class portion or lower-middle-class portion resting between the divisions of upper-middle and lower-middle respectively.
