Counterpoint: my parents and grandparents lived in the Soviet Union, and I now live in Ukraine, with many of Soviet systems still fresh in memory, if not in place. Priority was not placed in the human service, as much as you want to pretend through rose tinted glasses. The rest of your quote is generalisation of my words that I never said.

Update: oh wait, the fourth point is also blatantly untrue. Soviets literally swallowed a whole host of countries that happened to be occupied by Russian Empire at the time of revolution. Of course they wouldn’t need to invade them: the job was already done for them.
