I disagree. Big state universities are as popular as ever for people from all walks. As
@husky429 noted, a lot of kids in these parts seem to be attracted to UMD. Our oldest definitely was and one of my best friends has a daughter who is a freshman there now and loves it. I also know a bunch at Penn State and Pitt who also love them. In our town the southern state schools are also drawing a lot of kids now, especially Clemson, UGA, USC.
The thing you will find out is that many of the private universities are very generous with merit aid, which they use to woo the kids most desirable to them based on a variety of factors (frequently geographical diversity is one of them). That often makes them very price-competitive with, if not less expensive than, the big state schools, which are usually not as generous with merit aid for out of state kids. And many of the private schools do a good job of selling, and providing, customer service; whereas many of the state schools, in my experience, are more self-serve.
