Before the Industrial Revolution, life expectancy was about 30 years. That didn't mean 30-year-olds were senior citizens; it just means that, on average, 30 was a pretty good haul for most people. Sure, some of us lived to see 80, which is about the current life expectancy, but far more of us never managed to get past infancy, and those who did had to constantly worry about polio, scurvy, werewolves, inquisitions, the plague, the other plague, Groat's disease, and bottomless pits. All previous times to be alive were shittier times to be alive.
Today, thanks to things like improved nutrition and medicine, you can expect to live to be a senior citizen, you can expect to be a solid 4 inches taller than your ancestors 200 years ago, and if you live in the industrialized world, chances are you have a roof, running water, food, a clean living space, and fairly reasonable access to health care and so much porn. In a bygone era, your roof was whatever you made yourself, your floor was probably dirt, your food was what you grew, your clothes were what you made, and medicine, if you could get it, might be administered with dirty instruments, or it might be snake venom and opium on a cookie. They did weird shit back then. You don't even want to know what they used as fap material back then, either, but it probably involved some sweet goat heiney.
Of course, we still have a long way to go for everyone to share in this prosperity -- there are nearly 2 million homeless people in America today, and so many more living in poverty. But look how far we've come. Look at the potential that is here for all people.
Will we one day get our shit together and make sure everyone enjoys equal prosperity? Well, that might be communist, don't say that anywhere near a conservative radio host, but it's still a nice idea to think that one day we could live in a world in which people don't have to die in gutters for lack of proper mental and physical health care, nutrition, and housing. And we're way closer to that today than any other time in history. So look at you, no matter who you are and what you do. Does your life suck? It might; everyone's does sometimes. But it's better than what it could have been in so many ways. Remember that the next time you make it through a day without a werewolf eating you. The world is pretty awesome.
