So am I understanding this right?

MK Ultra proves to be successful, but requires the subject to be of a certain mindset/mental state.

Big Pharma comes in, and keeps people sick/on treatments. Big Media keeps them in a certain mood/mental state. Lax regulations allows for an unclean enviroments. Social engineering is done to keep people in the required mindset.

All of this is done to make MK Ultra / similar programs/tactics work on a larger scale?

Do some drugs, notably pot or LSD, work against this, as opposed to alcohol, which helps keep the cycle going?

For what purpose then? Are were bred like cattle for some specific purpose? What would the ultimate end goal be?

It's really a shame we cannot find a way to slip more of these subjects on Reddit without censorship. Reddit has a much, much bigger pool of people to crowd-source from.
