Increase University Participation==By 1900, there were less than 1000 colleges and universities in the United States. Most never had more than 1000 students. After 1900, education training began to be seen as a major need throughout the country. Already in the 1830s there were schools focused on education training but after 1900 they began to be integrated with colleges and universities. This led to growth in colleges providing training for teachers. Many of these education-focused colleges developed between 1900-1930. The 1930s Great Depression became a turning point for many colleges. Many of the state colleges depended on state legislatures to provide funding, while also keeping tuition very cheap. As legislative funding dried, many schools, even elite private schools such a Northwestern University, began to struggle. Some universities, such as Indiana, responded by becoming more focus on entrepreneurship in their education offerings, helping them to found new studies and disciplines. Others began to now increasingly depend on tuition to fund their activities. This kep enrollment somewhat low but helped diversify college funding.
The next key phase was the passing of the GI Bill, which provided an opportunity for every veteran to seek college education after the war. This meant that millions would be eligible for a college education. The Cold War also emphasized the need for scientific development, leading to increased funding for education. This now led to another expansion in colleges throughout the United States. The Higher Education Act now also created a federally backed system of low-interest loans to finance education, enabling most social classes now to participate in higher education. The 1960s also saw further expansion in college education through Lyndon Johnson's Great Society measures and programmes that helped expand and increase education for vocational training and professional training such as in dentistry. By the late 20th century, for-profit universities began to emerge as a new phenomenon due to increased low-interest lending given that enabled higher rates of higher education participation.
