Man Vs. Hahem...!!

Man has a partnership with G-d, Hashem is ultimately responsible for injustice but man, must make a effort. There are those that work hard all of their life to make money but when their riches are lost they become sick and wrathful and die, what's the point? Your supposed to enjoy everything that G-d gave you. If you can't have everything so hakol hevel, so just die anyways. Everything that is made by man can't be perfect. Man isn't perfect and everything man ever Does will be perfect, and G-d is the one in charge.
