poor people (evyonim) today

I think that there is fundamental shift in general expenses that should be reflected in halachic charity laws. The shift is from 90% of income being spent on food to housing, health insurance, tuition, utilities, etc.. with food accounting for less than 10% of yearly expenses for an average family.

For example, on Purim the din of Matanos Le'evyonim requires one to find an Evyon, defined as somebody that does not have enough money for 2 meals. The requirement is to give that person funding for two meals. I think that today, especially in a world where they have dollar menus at Mcdonald's, the definition should be revised to something else. Maybe someone who doesn't have money for his next mortgage, or to pay health insurance. Also, the obligation should be to give that person money to fill that need. Maybe to pay his mortgage or something. It definitely needs to be reexamined in light of the changes in spending needs of modern society.
