His book The Meaning of Money, published in 1909, was considered to be an important and pioneering analysis and explanation of the financial organisation of modern society.

[1][2][3] After graduating Withers was employed "for a short time" as an assistant master at Clifton College, a public school in the city of Bristol, after which he worked as a clerk at the Stock Exchange.

[7] During the years preceding World War I Withers was one of three influential economic journalists writing for British journals, alongside Kitchin, his colleague at The Times (and later with The Morning Post), and Arthur W. Kiddy of The Standard.

It was described as "a great book, epochal in finance", in which difficult concepts were presented "clearly, concisely and temperately" and with "scholarly precision".

[4] A review in the Manchester Guardian characterised The Meaning of Money in the following terms: "No common measure of literary accomplishment, a lucid, forceful and pointed style, and a great store of material for apt and often amusing illustration have lent both grace and charm to a work of quite exceptional utility".

[4][1] After the success of The Meaning of Money, Withers continued to write books dealing with aspects of finance and financial institutions, written in a lucid style suited to the general reader.

Foxwell adds that Withers' writing "is the kind of simplicity we often (perhaps only) find in the great masters: the result of a firm, clear grasp of essentials".

[1] Withers last book was published in 1939; The Defeat of Poverty was described as "a stimulating and provocative contribution to the literature of economic recovery of the period".
