The community college in the town I grew up in was $17 a credit hour in 1997. Adjusted for inflation, that's $26.17 a credit hour. A 4 credit hour class would cost $104.68. That's something many working people could cover to take a class here and there to further themselves or their job prospects. There were subsidies for those who couldn't afford that as well.
That same community college today? $132 a credit hour. That's a 500% increase over inflation.
This isn't being talked about because university costs affect middle and upper-middle class people more, so pundits and the media are going to be more affected.
But this gross inflation has definitely pushed working class and poor people out of the classroom and that's a terrible thing for society at large.
