People getting freedom? Are you serious? Life is tough for many people. You can't get freedom when you pay half of your salary in taxes and 1/2 of the rest in rent and bills.
Well, life is tough for many, but at least people have more choices than before. Slavery was about dehumanization and forced hard work. We can't compare slavery with modern work, at least we can choose on what & where we wish to spend our salary. So I guess we can say we have more freedom in the 21st century, but it could be much much better for all the people in the world... if only there was less evil and more goodness.
Not everyone has a choice. People who are born in rich countries, really have a choice but those who are born in poor countries, especially in poor families, don't really have a choice. Many families are so poor that when their kids grow up a little bit, they are forced to start work in unskilled jobs to earn some money, they also don't get a good education and this kills their future. Then their parents get old and they have to take care of them (it's how it works in my country) and this is also a burden on their backs. Many people grow up, start working, then take care of their parents, then they also get older, they have no wife, no kids (who wants a poor man?) and die alone, old and in poverty.
