We have domesticated crops over a very long period of time, like tens of thousands of years. And crops get - seeds get carried. Sometimes, if they're very small seeds, they get scattered off trucks. Pollen travels.

There may be some backward countries where the mass of the people are on a subsistence level and where, as an aftermath of wars or partial crop failures, the standard of living has to be drastically reduced, but this certainly is not the case in our prosperous nations.

At Horace Mann High School in affluent Riverdale, New York, one of the top schools in the country, those who receive double time on tests are plentiful enough to qualify as their own segment of the student body. Known to their peers as 2Ts, they participate in the same activities, get the same grades, and attend the same range of colleges.
