This Court further laid down the principles in that regard as follows, at p. 92: "The principles which emerge from the above discussion are: (1) that in the fixation of rates of wages which include within its compass the fixation of scales of wages also, the capacity of the industry to pay is one of the essential circumstances to be taken into consideration except in cases of bare subsistence or minimum wage where the employer is bound to pay the same irrespective of such capacity; (2) that the capacity of the industry to pay is to be considered on an industry cum region basis after taking a fair cross Section of the industry; and (1) 599 (3) that the proper measure for gauging the capacity of the industry to pay should take into account the elasticity of demand for the product, the possibility of tightening up the organisation so that the industry could pay higher wages without difficulty and the possibility of increase in the efficiency of the lowest paid workers resulting in increase in production considered in conjunction with the elasticity of demand for the product no doubt against the ultimate background that the burden of the increased rate should not be such as to drive the employer out of business.
