Humans activities usually/systematically lack of quality, because many reasons: People lack of enough energy (lack of money, time, resources, enough rest,...), lack of coordination between individuals, lack of intelligence/planning, lack of training (underskilled), lack of powerful tools, corruption (doing risky shortcuts for example), lack of attention/focus (distracted), lack of motivation (will power),...
We desire/try (hope for) high increasing quality in all our activities/actions.
