when Thomas Jefferson was writing the Declaration of Independence. He took the statement but he realize that he couldn't assure everybody to have property. So he said the pursuit of happiness, because of all the horrible and Intolerable Acts sugar acts and facts that were put on them during British rule. So the pursuit of happiness is that they will be able to be happy and do whatever they want within the law so they have more freedoms and they don't have to do things like taking soldiers anymore and they won't feel like they're suffering. And because they couldn't ensure that everybody was able to own land they changed it for that reason.
