No math has not changed, instead something far worse has occurred - the royalty stream has stopped as books are good year after year and unchanging - as it should be - HS math, Algebra and geometry is a stable topic. So these new books are created and the teachers who wrote them want them sold, the publisher wants them sold...need I say more. there is a need for a public domain set of math books, year by year, with online ability to read. Such books can have lives in decades and the only changes will be typos etc and wear and tear. That would give books printable in runs of 100,000 or more = low price.
The conflict in the system allows this, even promotes it. In college you even have profs printing books to sell to students directly.
You want to get laid, you learn to run with the pack, conform and try to be alpha male/female. As we see, a large portion of our youth do this. An offshoot of the alpha male path is football = guarantee of plenty of sex. The girls flock to them = that is what they want, laid and kids. Our co-ed system is complicit in this.
In Singapore the youth are prevented from these paths by more restrictive parents and social rules. I am not sure how separated the sexes are in Singapore schools?
So if we want to eventually be a nation in decline - carry on. High school teachers are greedy and incompetent and sacred = can not be fired for being bad.
There needs to be a balance between the weakness of right winger politicians to keep wages balanced and give cost of living adjustments(COLA) + 2-3% real wage increases (RWI). Some of them are left wing and willingly give COLA + RWI of 2-3% annually. So if you give unionists COLA and RWI of 4-5% annually you have a mechanism to ramp ahead of the rest of us and automatic inflation. See what this did to Detroit in the USA and to the American auto unions. It gave a gift of all those autoworkers jobs to the Japanese and Koreans who built roll-on-roll-off (RORO) cargo ships so the old time high freight time and damage costs of importing cars from Japan and Korea were dramatically reduced. These unions lost 90% of their jobs through greed and look where Detroit is now.
The truth is, you can not give one side all the $$, be they union or management. A balance must be struck. What good is it if the company goes broke and the high wages the union wanted are now gone.
Here in Canada an ex-union member is almost unemployable because if he is on strike, and working for pocket money the company know that if he is recalled he will not show up for work the next day = zero notice to the company that hired him. So reference are checked with care, great care.
Metal and coal prices vary greatly. When metal prices fell, there were no super profits any more = so why tax them. A mine is not like a factory. Most mines are good for 10-15 years and are then exhausted. (a rare few last a long time indeed). Coal is common, so when people dig too much the prices fall - as we have seen. What is needed is a way to reduce wages when prices drop and increase them in super profit times. That would allow mines to make money when prices drop instead of closing the mine = zero wages or sales.
Too many left wing miners think money grow from the ground, and too many right wing mine owners want miners to eat coal dust. A middle ground where both live and the money is shared, but this would need statesmen current pols in all countries are just greedy grabbers, like most mine operators as well as mine workers. You need a steady 20-30 years of reasonable wages all the time, in places of high wages- Laid off - high wages - laid off repeat until you die.
True, we run "popularity contests". The capability to manage public affairs is never shown to be present at all.
I seem to recall the Mandarins in China in olden times, had examinations for the civil service. I wonder how the subject of testable qualifications being required before you are nominated passes muster? Also secret ballot, not a public show of hands. The show of hands allows bribers to observe bribees earn their bribe. US Congress and all elected officials need secret ballot.
Alive and well down under... Unless they get a pet judge, the judge will crucify them. I suspect all this hemming and hawing is to try and line up some sort of charge sheet that will syand up to scrutiny. They should give it up as a bad job, and dialog with anonymous to settle the underlying flaws - or they will die the death of 1000 bites.
