Does anyone else think the Russian failures at the start of the war unlikely to be due to miscalculation alone?

This invasion has proved to be a gold mine of intelligence for the West in terms of Russian preparedness, and how they have obviously been relying on the sleight of hand and image making to mask their ineptitude, and poor training while relying on vintage tanks and equipment. They were totally unprepared for a much better fighting force in the form of the Ukrainians.
With these glaring miscalculations now exposed, any individual(s) with a modicum of intelligence could not help but ask the question....."if Russia's military is THAT outdated and poorly trained and equipped....where has all that money gone.....in terms of billions. I could only opine with one word. "Oligarch." It would appear that their collective arses have now been exposed. While they swim in champagne, caviar, yachts, and villas, the common Soviet, ever loyal to the Mother Land, suffers and sacrifices, paying in like the dedicated mind bent souls that they are to their communist ideals that have drown them in propaganda since they were born.
It's so sad......time for a new revolution.

The disparity is in the motivation; people are so quick to forget the human factor of war yet it is the most important factor as for most of human history it was the only factor.

On one side you have a force that is largely being forced to fight. Despite their advantages they largely and simply do not have the will nor the want to be where they are and to do what they are doing.

On the other side you have a force that is fighting for their lives, for their families, their freedoms, and their national identity. They will fight to the fucking last and if they run out of ammo they'll start throwing rocks.

Of course Russia was in for a bloody nose. It was stupid for anyone to expect anything less.

An autocratic Government runs on propaganda, and after awhile they believe their own lies and propaganda. Meanwhile, they will cut funding to necessary accounts, such as power, military, etc.

Yes.

In Putin's grandiose memories of the Good Ol' Days, Hungary's Freedom Fighters caved and fled in exile at the sight of Soviet tanks rolling down the streets back in the 1950's.

yep

My understanding is that corruption and a poor officer corps did that. How could they send hundreds of vehicles without logistical support?
