According to research, if you look at the wages of workers who were 30 in 2014, when accounting for inflation, they are actually lower than the wages of those who were 30 just 10 years ago. This research has also found that the 30 year old workers today are actually paid the equivalent to what people made back in 1984. Even worse, those who are 30 today without a college degree make even less than what people their age made 30 years ago. Despite this lack in wage growth, tuition for public colleges has actually grown by nearly 30% just in the last 10 years.
