Biden free college a reality?

[bluebooger]

A fully privatized system will always be more efficient and cheaper. 

I don't know if I agree with that                     
because I'm not sure how a privatized system would work 

do students have to buy books every year for every class like they do in college ? 
do they have to buy a microscope for biology ? or maybe purchase a lab kit like they do at straighterline ? 

wouldn't privatized schools make more money by cramming more students into a classroom ? 
wouldn't their philosophy be "let's get 40 students in a classroom and have them all score B- and C+ instead of 20 students in a classroom and all score A+" 
each student would get less individual attention but wouldn't the school's response be "as long as they passed, so what ?"
