He is not oblivious. He wants the repression, scarcity, misery, and death that his preferred system inevitably produces. He knows not to advertise it, though.
The entire point of socialism is to inflict your enemies with all the suffering.
One, it inevitably leads to some form of fascism or authoritarian control. The sharing and fairness fairy tales told by those promoting socialism (in whatever form) sound great. But the reality is in any society there is a whole spectrum of motivation. Some people are quite content to sit around and be taken care of at some minimal level. Others are motivated to work hard, to better themselves, better their situation, provide for their kids, etc. The problem is the people towards the productive end of the spectrum generally don't want to share the fruits of their labors with those towards the lazy end of the spectrum. They start looking for ways to keep more of what they earn and produce. Then the "benevolent" socialist government must step in and help ensure "fairness" - which inevitably leads to fascist, authoritarian policies and measures. The net of it is, socialism may start off sounding good, with a groundswell of popular support...but eventually it must be enforced and imposed on an ever more unwilling and restive populace. In the end, the government must take control of virtually every aspect of society.
The second thing to realize is that there really are only two kinds of people promoting socialism. There are the naive masses who actually believe the sharing and fairness fairy tales. These people are ignorant of history, they believe the lies being told to them, and they are unable or unwilling to perform the simple thought experiment that would show them socialism is a failed idea. The other type of person who promotes socialism is fully aware of these real characteristics and shortcomings of socialism. Far from being repulsed by them, they want them. They see themselves as being part of the system. They want the government to have virtually unlimited power and control, because they see themselves as at the levers of some of that power at some level. These are the leftists who think they are the smartest people in the room, that they know best. They can't wait to impose their "brilliance" on the rest of us.
Oh, and to any leftist/lib lurkers out there reading this and telling themselves "that's not how it is" or "he's wrong, he just doesn't get it" or even "he's just too stupid to see it" - No. That is in fact exactly how it is, you are precisely the problem, and you're proving my point.
