That's a nonsensical statement. Slavery, feudalism, and neoliberal states all attempt to produce as efficiently as possible, but they're obviously quite different...
The internal mechanisms are quite different, yes, however, the inputs and outputs are for the sake of this discussion, identical. The people, regardless of the system, would probably be performing the same types of operations. I’m not sure you read my original point as I intended it to be understood. A worker making tires under authoritarian communism is still going to be making tires under democratic capitalism - the differences in this worker’s experience may not be the result of these political and economic systems but rather policy at the corporate, departmental or state level which are not unique or exclusive to a particular government or economy.
Any system will self propagate at the expense of other systems and individuals like workers.
