If MV = PQ is so well tested, why are there still Keynsians?
There aren't, there are neo-Keynsians.
The Keynsians say, "In the short term (so short that we can't measure it accurately), increasing inflation might still improve employment."
In other words, the dispute isn't about whether the equation will become balanced, but how long it will take for it to become so.
Never mind that back in the prosperous '50s "good ol' days" taxes here were even more progressive than they are now...
I prefer progressive taxation, but this is a myth.
Back in the 50s, there were so many loop-holes in the tax laws, that almost no one paid the full rate. To pay it, you basically had to get your entire income as salary (which is why some athletes were among those in the highest tax bracket). I'll bet you can think of ways to avoid that kind of tax, structuring your income to not be salary (or hourly).
Looking at my undergrad experience as a whole, i learned waaaay more in 3-4 semesters of co-op / hands on training than I did in 4 years of classes.
If you really didn't learn anything in 4 years of classes, then you either failed or your school failed you.
And I'm not talking about your grades.
There's no shortage of qualified developers.
Sadly, looking around at my fellow developers, there sure seems to be.
And it's not a problem that will be solved by 'less' education.
What is the bare minimum a code monkey must know so that he can do professional code monkeying?
It really depends. In some cases, all you need to do is be able to set up a Wordpress site.
But if you mean a science like biochemistry or physics, where you do controlled experiments, then no, it is not a hard science. Some people differentiate "hard" from "soft" sciences.
Where do you categorize astronomy in that way of looking at things?
I seem to be beyond "no understanding"
That can be cured, go take an economics class or read a book.
as a physicist I always feel insulted when economics is called "science".
That can be cured too....give up your stupid ego. Physicists don't know everything, or even most things.
