They measure success by how long you stay on their page. The slower it runs, the harder it is to get it to do what you want, the longer you stay on their page.

Profit !

You're telling me that the teachers are so poor quality that if they don't teach the material that will be on the test and nothing else, the students won't pass the test. Teachers that poor should be fired. There are a great number of people in the general public who need jobs and could teach better than people currently employed as teachers; they'd have the additional advantage of not already having their minds corrupted by the garbage that teachers learn in normal schools.

A student who has learned nothing in a year has been seriously damaged by his teacher, who should be fired before damaging other children.

Tooth decay starts early. A great deal of it occurs before puberty, during which time children crave sweets and haven't really gotten the knack of good teeth brushing. Optimistically, 42% of Americans have had a cavity by age 11.

The idea that primitives don't live long enough to have tooth decay problems is silly.

A typical bachelor's degree in engineering involves no more than 5 courses per term for 8 terms. Discard the wasted 1 course per term of humanities or other irrelevant drivel, that leaves 32 courses total, each of which consists of little more than learning the contents of one book. Look at a college catalog and degree requirements, figure out what those 32 books are, buy them and learn the contents. Buy a computer and teach yourself enough programming to be able to handle some problems in your field, also learn some of the standard software in the field that's freely available (or available as student edition), like SPICE. You are now short of a college education's "well-rounded rich engineering base" only by the absence of some lab courses.

About $4000 plus room and board for the time it takes to learn the material, some hands-on experience, done. As a bonus, no exposure to depraved fellow students.

It's not 1937 any more.

China's aggression is limited by what they think they can get away with.

Natural selection happens in seconds for unsuccessful prey animals, and sometimes in a single generation in cases of newly introduces disease.

For something operating relatively fast, consider the population of American elms compared to other trees after the introduction of Dutch Elm Disease.
