Not all of them are. There are many poor people who are white. But, honestly, anyone born in the United States is quite privileged in the sense that their country protects their rights. For example, the entire Constitution (amendments, due process, etc.), social benefits, homeless shelters, etc. Other countries are not so lucky. To put this in perspective, in a third world country, such as Saudi Arabia, women were only granted the right to drive about a year ago. Also, if a woman taught a child to read, they would kill her and the child, because they feared that women would educate themselves and share that education. In a second world country, like Thailand, if you drop your money, you can't chase it, because if you step on it to catch it, it's like stepping on the royal family and you'll go to jail. Even in other first world countries, such as South Korea, people (including children) are overworked. They go to school 6 days a week, from 8 am to 9 or 10 pm and when they get home, they study another 4 hours. In other words, they have a 16-hour school day. Also, if you're overweight / not attractive, you can't even be hired for a job, which is why plastic surgery is so common there. Because of all the stress, the suicide rate is EXTREMELY high. In addition, men in South Korea are required to join the army. Women don't have to do it, but they can do it if they want to. Another thing is that I saw a video of these people interviewing a single father in South Korea. Single parents are VERY despised, even when compared to single mothers. Most people pressure parents to leave their children in orphanages, instead of taking care of them. If a father is legally single, he cannot even register the birth of his son, only the mother can do it. So, if a child was born out of wedlock and the mother decided to get up and run and leave the baby and the father, the child cannot become a citizen. However, if the father and mother are still legally married, but the woman ran away, he and his son would consider themselves lucky to be able to become legal citizens. In addition, in general, there are children, currently, starving around the world while we sit here discussing who is more / less privileged.
And instead of donating them to help them receive their BASIC HUMAN RIGHTS, you sit here writing on the Internet about how your life is SO hard and oppressive. Trust me, if I really were so oppressive, you wouldn't say that. You wouldn't even be on the internet. So, as an American, I say:
Check your privilege.
Edit: Also, if we are on the issue of whites being systematically privileged, not all were like once slavery ended and we began allowing immigration, many of the white immigrants were treated as badly as blacks. In fact, once the Irish arrived here, whites and blacks treated them EVEN MORE THAN blacks.
