Somebody tell me please why S = Y - C - G and not S = Y - I - C - G.

It's only me who can't understand this moment?

Investing make up the top notch hemisphere of wealth.
That's the more reason one should save and invest to

So if investment = savings, why would investment fall when interest rates increase? Surely by this logic higher interest rates means more savings and therefore investment would also hace to rise
