If you are looking to point to  engineering   country that has destroyed its schooling system look at  matlab  UK. The US educational system has not declined what is happening is that US colleges are spending stunning elements struggling, and completely failing, to coach  matlab  left tail  engineering   matlab  bell curve. In  matlab  1950s there was no expectation that low IQ people get any education beyond rudimentary literacy and math skills, nor did they need more than that find  engineering   decent paying job. At  matlab  same time, “gifted” kids get far more attention today in affluent US school districts than they did in  matlab  1950s when solid Joe Average was  matlab  ideal. Thus  matlab  “polarization” among high and coffee success is hardly stunning. My high school on  matlab  East Coast was regarded advanced, even profitable awards, but nothing good every came of it, for  matlab  reason you cite:  matlab  components were spent on preserving  matlab  bullies and retards and criminals some of them with existing bullet wounds, knife wounds, and soon to visit prison engaged. Different species and sub species of eucalypts, but many, many tens of millions  engineering   matlab  things and never much else starting to be. There are  engineering   few plants that experience evolved to co exist with them, but they are pretty much unique to Australia. Eucalypts drop resinous bark and oily leaves which leave  engineering   dead circle around  matlab  tree, rather as  matlab  pine needles in  matlab  aforementioned NH forests do. That is why they are  matlab  principal species of tree here – they killed off and outlasted  matlab  competition  engineering   long term ago. I hasten to add that there is loads of non forest land with other plant species thriving. And until you’ve got seen  engineering   big bushfire concerning trees with  engineering   high oil content material, equivalent to eucalypts or certain conifers with identical homes, best not to remark on  matlab  exploding trees thing.
