The upper class is a group of people who have a lot of money and resources. These people are usually very wealthy, and they have lots of opportunities and advantages because of their money.
Think of it like this: Remember when your parents took you to a toy store and you could only pick one toy? Well, the upper class can have all the toys they want, and they can even buy a whole toy store if they want to!
The upper class is usually made up of people who have inherited their wealth from their families, or they might have earned it by being successful in business or other careers. They tend to be well-educated, well-connected, and have a lot of influence in society.
They live in big houses, drive expensive cars, wear fancy clothes, and go on exotic vacations. They can afford to send their children to the best schools and provide them with all the opportunities they need to succeed.
Being in the upper class also means having access to things that other people might not, like good medical care, private clubs, and exclusive events.
So, in short, the upper class is a group of people who have a lot of money and resources, and they can use their wealth to give themselves and their families lots of opportunities and advantages in life.
