NOT A TEACHER
(1) "This is greed at its most basic level" = this is an obvious, animalistic
example of greed:
At dinner, a cruel father takes 3/4 of the cake and lets his wife and children share
the remaining 1/4.
(2) But greed is often on a higher level:
In some countries, there is little money to pay for schools, bridges, etc. because
the rich people refuse to pay any taxes. This is greed on a different level: it is not
so obvious (as the cruel father's greed), so it is harder to see and understand.
