Shakespeare was not born into the upper class; his father was a glove-maker and his mother came from a family of farmers. However, through his success as a playwright and actor, Shakespeare accumulated wealth and social status, allowing him to live a comfortable lifestyle and interact with members of the upper class.
Your question is unclear. If you mean "What class of people would watch Shakespeare's plays at court?" the answer is the upper class--royalty, nobility, and their servants. If you mean "What class of people are portrayed as being at court in Shakespeare's plays" the answer is the same. Indeed you could have asked, "What class of people are at court?"
About everyone except the very poor. People went to be seen especially the upper class.
Upper class.
During Shakespeare's life nobody questioned that William Shakespeare wrote his own plays. It was taken for granted that a famous actor would be able to write famous plays, and that the company that owned the plays (The Lord Chamberlains Men) employed the actor / manager / playwright who wrote them. About two hundred and fifty years after Shakespeare's death, a book about leisure yachting suggested that Shakespeare probably couldn't have written such good plays (J C Hart The Romance of Yachting. 1848). The argument was that Shakespeare was not Upper Class, and only Upper Class people are clever enough to write really good plays. The argument appealed to lots of other Upper Class people (for obvious reasons), and soon there were lots of people suggesting various Upper Class folk who might have written Shakespeare's plays for fun, but then put the name William Shakespeare to them - because they didn't want to be identified as the author. Any Upper Class person would do. So some people said the Earl of Oxford wrote Shakespeare's plays (the Earl of Oxford wrote dreadful poetry, and died before King Lear was composed - but Upper Class folk can write plays even after they are dead). Some people said Francis Bacon wrote Shakespeare's plays (Delia Bacon began this theory, even though Francis Bacon didn't even like plays). There were lots of Upper Class people who wanted an Upper Class person to have written Shakespeare's plays; and they wrote lots of books about it. The scholars didn't bother much with the idea, scholars know that there is no evidence to suggest that Shakespeare's plays were written by anyone else but Shakespeare. The Authorship Debate is rather like Intelligent Design: there is no evidence in favour, and lots of evidence against - but people know what they want to believe, and are happy to ignore the facts - or even tell lies - in defence of their case. The Authorship Debate has become popular again lately because to the film Anonymous, which suggests that the dead and not especially intelligent Earl of Oxford wrote Shakespeare's plays. In the film Anonymous, there is even a suggestion that the Earl of Oxford may have collaborated with Christopher Marlowe - who was also dead. Shakespeare's plays were written by two dead guys working together! There is no Authorship Debate. There is a bunch of seriously snobby guys who really don't like the idea that Shakespeare was an ordinary guy with a basic education; they want Shakespeare to be Upper Class (like they are). Sadly, being dumb has never stopped anyone from being accepted as a prophet. Think Ted Haggard.
low class, middle class, upper class/high class
In Shakespeare's time, the upper class had more wealth, education, social status, and political power compared to commoners. They were often landowners, nobility, or royalty, while commoners were usually peasants, artisans, or laborers. The upper class had access to better living conditions, entertainment, and opportunities for advancement, while commoners faced poverty, hard labor, and limited social mobility.
Upper middle class
The upper class limits are the greatest value for each class. For instance if your class is 10-20, the upper class limit is 20.
