The Matter of Giving

I find this text in Exodus 30 interesting: 14 Every one that passeth among them that are numbered, from twenty years old and above, shall give an offering unto the Lord.

15 The rich shall not give more, and the poor shall not give less than half a shekel, when they give an offering unto the Lord, to make an atonement for your souls.

Everyone seems to have been required to give the same amount no matter how much they had or did not have. Everyone was required to contribute. I wonder what would happen if we, as a nation, followed this simple godly principle. No, it is not merely a principle rather a mandate.
