I do not know about "personal wealth", but private property is indeed a foundation of freedom.
I do not know about "consumption", but hungry people rarely can stay free.
In any case, you are confusing cause and effect here, again.
Freedom to hold private property causes personal wealth (with all its excesses). Same freedom causes material abundance, that leads to material (over?-)consumption. But private property, or freedom, do not _need_ overconsumption or excesses to exist.
(btw, "shto" would be a slightly "vulgar", "hurried" pronunciation. Proper pronunciation for this word is "chto" :-) )
