You must be blind then if you can't see that the Start Button and the Start Menu on the classic desktop is no longer there.
Sorry sir, but it is you who is blind. The start button is there, it's just hidden until you move your mouse into the corner... you know just like you did on Windows 7. The start menu is also there, it's just had a radical overhaul. Everything that most
people used the old start menu for is replicated on the new start screen. Launching pinned apps, picking apps from an app list, searching for and launching apps, accessing control panel (settings), etc. Anything more technically literate people used to use it for can now be found in other ways. Win key + X for example.
At the end of the day, this is Microsoft's product. Buy it or don't, it's up to you.
