Do this: pick something where government has little involvement and compare it to something where government has a ton of involvement. How about......video games vs education? Sure government has some involvement in video games, but generally it's not market-distorting. Government has tons and tons of involvement in education at all levels. Compare them on these criteria: costs, availability for consumers, achievement of proposed goals, innovation, and any others you can think of

Look at things like how video game costs have consistently dropped while education costs have consistently risen. Or how video games have consistently achieved proposed goals while education is consistently failing its proposed goals. You can find things that are more market oriented than video games and things that are more centralized and controlled by government incentives than education, but not by much
