Youth rights. We believe it’s acceptable for youth to enlist in the military and “die for their country” at the age of 18, however they can not legally drink alcohol. In most states, youth can work (and pay income tax) from the age of 14 but cannot legally drive or vote. In the future, there may be a movement to lower the voting age to 14 or eliminate age-based discrimination altogether.
Animal right. Today, most people consider raising and killing animals for meat acceptable. Fur has mostly fallen out of fashion, but it’s still worn by some. In America, eating “pet” animals (dogs, cats, etc.) is distasteful, but we do not feel the same way about “meat” animals (cows, chickens, pigs, etc.). Over time, our view of “meat” animals may move closer to our view of “pet” animals, especially as we discover more about consciousness and the brain.
Non-violent drug users rights. You can currently be imprisoned for ingesting a substance that grows in nature. That’s a bit strange if you think about it. This group has slowly been gaining support since the 1960s but still enjoys less political support than the gay rights movement has today, at least in America.
The right to (end your own) life. Suicide and euthanasia are illegal. In the future, we may believe that people who wish to end their own life should have the right to do so.
Immigrants. In many countries, immigrants treated as an under-class and don’t enjoy the same rights as citizens.
Workers rights. Laborers in many countries that import goods to America work under conditions that are considered unacceptable and are illegal in America. As borders between countries become less significant, we may not tollerate this discrepancy.
Basic human rights. Billions of people around the world live in poverty for reasons that are not of their own causing. In the future, we may no longer consider this acceptable.
I could go on but I’m starting to get depressed.
