We need investors who actively invest, by evaluating the companies, so that more money goes to good companies and less money goes to bad companies.
The index represents the current batch of the top 500 good companies in recent times as decided by the active investors. The index is re-balanced as the preferences of the active investors change.
So, if there were no active investing, then investing would be completely pointless.
CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around.
The activities introduce students to underlying concepts such as binary numbers, algorithms and data compression, separated from the distractions and technical details we usually see with computers.
CS Unplugged is suitable for people of all ages, from elementary school to seniors, and from many countries and backgrounds. Unplugged has been used around the world for over twenty years, in classrooms, science centers, homes, and even for holiday events in a park!
It's not entirely true that inflation effectively results in a pay cut.
It's true only if you are buying the exact same things today, that you were buying, say a decade ago. This is true for some things such as food, housing etc.
However for other things such as computers, gadgets, medicines, cars, etc. are much better today than they were before. For these things, you get much more for the same price(taking inflation into account).
For example, phones used to be only communication devices; but now they are also a camera, entertainment device and even a computer. Others, such as medicines, they have become cheaper and much more effective. In short, improvements in science and technology beat the effects of inflation.
In some markets it can actually cause a deflation.
For example, computers used to cost thousands of dollars, but now you can buy a much better one for a few hundred bucks.
Inflation is bad, only when stuff that you buy doesn't improve over time.
Perhaps one could even show that inflation is somehow related to the introduction of newer and better products in the market. For example a new car, with a more fuel efficient engine, will likely cost more than the old ones.
However I don't have enough evidence to justify this claim.
