The author makes several statements which are not explained convincingly using any of the economic tools. Some of which are mentioned here. It is wrong to state that there was no inflation before the abolition of gold standard. Economies did experience inflation during the period when gold standard existed. Secondly, it may not be wholly correct to say that the institution of interest is solely responsible for low wages being paid to the labourers.
Wages are a function of demand and supply of labour.
In fact, it may be pointed out that during the periods in which the demand for labour is low due to low level of investment in the economy, the rate of interest has also been found to be low. Thus a high rate of interest is not the cause of low wages in such cases. The author makes sweeping allegations against all the economists and calls them as paid agents. This is not true because many of them are ignorant about any alternative economic system and they work under a mental framework in which interest is accepted as something which is not sinful. This is the reason why they do not think of a system devoid of interest.
