the current economic level is the benchmark of prosperity, from personal to state. i think all the disciplines of science will lead to the economy
Absolutely everything leads to economy but that does not mean everyone must have to study economics all in the name of trying to do well economically. If that is the case, we may all just end up stuck with only economics with other sector being denied.
Economics works with every sector and understanding it basically comes with some experience and some overall knowledge gained gradually in real life situations and that alone is enough for anyone who is intelligent to understand all that is needed to know while leaving the professional aspect of it to those who are deep in it and studied it as a course.
