The way I see it, is that in order to be needed by society, you don't just need to work an essential job, like a teacher or bus driver. You also need to be able to do a task that a very small percentage of people are able to do. If asked what jobs are essential people will probably be quick to say something healthcare related as their example, because it saves people's lives. I find this somewhat bizarre as a huge amount people will always choose to live unhealthy and sedentary lifestyles, despite knowing what's bad for them. And that's the root cause of obesity and heart disease. It would probably actually be better for people's health, to ban all advertising of any food/beverages (bar things like vegetables!) than to bother investing any more in healthcare. People will also probably say teachers are essential. Yes they are, but they're easily replaceable. Yes, you can't just put anyone teaching a class just because they've knowledge of a subject. But what percentage of the adult population could teach kids the basic essentials they need to know? It would be an incredibly higher percentage of the population that could this that in comparison to the percentage that could fix the problem that you called an electrician for. Are researchers really needed anymore? Researchers for what? creating better AI sexual fake images, making bombs, guns, drones, trying to develop dementia drugs that will never exist. Imagine if we could properly implement every technological advancement that's already been made fairly throughout society. Based on this way of thinking, I view the most essential jobs that I can think of right now as below, along with other professions closely related to these: engineers plumbers nurses carpenters electricians farmers mechanics builders doctors paramedics/EMTs
So do I. The human interaction is something I took for granted. Any form of human interaction puts you into a slightly different head space. With the self service, you go into and come out of the shop feeling like nothing happened.
I agree teachers can be easily replaced. In my state all you need is to be a citizen, have a BS or BA in the subject area you want to teach with a 3.0 GPA, acquire a state certification certificate, pass two different Praxis tests, obtain a Department of Human Services Child Abuse History Clearance, pass a Pennsylvania State Police Request for Criminal Records Check, and pass a Federal Criminal History Record Information report, then be fingerprinted and photographed. That gives you a provisional Level I certificate which is valid for six years. Once employed you only have to be professionally evaluated twice a year for professional instruction and classroom environment, meet the code of conduct for educators, abide by the educator discipline act, and conform to the professional standards and practices commission laws. During those six years you must have completed satisfactory service verified by the chief school administrator of the employing school and have acquired an additional 24 post baccalaureate credits mandated by your particular area of expertise and be deemed of good moral character. Then you can apply for a Level II certificate. After acquiring your Level II certificate and in order to keep it you only have to abide by all the moral and legal requirements stated above, be continually professionally evaluated twice a year, each year of employment, and earn an additional 180 hours or 6 college credits every 5 years whether employed or not. While employed you may be fired at any time for immorality, incompetency, intemperance, cruelty, negligence, sexual misconduct, sexual abuse or exploitation, and criminal conduct. Simple. But we really don't need all of those requirements, anyone can be a teacher.
Those requirements would certainly winnow those that don't take teaching seriously from those that do. I hope that most states have qualifications such as those you listed--- but I doubt if they do.
I refuse to use self service checkouts and when directed towards them, I just tell the staff that I will happily use them when they send me a salary cheque every month. When they tell me they have no cashiers I give them 2 options, find one, or find a staff member to put all my shopping back on the shelves again.
I forgot to state that those requirements are for public school. Private school teachers only need a 4 year college degree and a Pennsylvania teaching certificate in a specified area. Private schools are free to hire anyone without consideration of their morality, competency, intemperance, cruelty, negligence, sexual misconduct, sexual abuse or exploitation, or criminal conduct.
Oh. So that's why the republicans are so insistent on vouchers taking money away from public schools. They can then see to it that right wingers and trumps / republican ideas / philosophy are taught.
