SYMPOSIUM 75 a) the structure of industry has substantially changed, with a broadening of the industrial base, key and heavy . sectors, though crucial gaps still remain ; b) the proportionate contribution of industry has not changed significantly, though the absolute volume of production has certainly increased; c) the share of the tertiary sector has increased, which is an indication of the parasitic nature of development of monopoly capital on such a poor industrial base. Incidentally, it was observed that this growth of the tertiary sector has led to the growth of the white collar workers, who are in increasing numbers organising themselves into trade unions and fighting side by side with the industrial workers; d) the pattern of industrialisation has been uneven and such as to leave the problem of regional disparities essentially untouched; e) along with regional disparities, sectoral imbalances have also grown; f) during the last phase of this period, it has been noticed that the problem of markets which for a short period during the Second Five Year Plan and the early part of the Third Plan was becoming less acute, has emerged very sharply again and reached an accentuated form. Regarding the impact of this development, it may be noted that the size of the working class in the organised sector (factories, plantations, mines and transport) has grown substantially, though their share in the total labour force has changed only marginally. Though the level of living of the working class improved till the mid-50s, it tended to decline since the early 60s. A large segment of the working class is struggling hard to maintain their real wages at pre-war levels. Consequently, the increases in industrial production have largely benefited the capitalists. Though the condition of the working class is better than that of the ever-increasing army of the unemployed or that of the agricultural workers, its revolutionary potential and leadership in the democratic struggles can and must be developed through proper political-ideological education and relentless struggles against economism among the working class and trade union organisations. The real income of the middle class employees has also continuously deteriorated over the two decades so much so that militant trade unionism among the middle class employees has also developed. These middle class movements are becoming part of the working class movement, not dominating it, but inspired by the greater struggle of the working class. This is important in the context of the deepening economic crisis. Composition of the Bourgeoisie A differentiation has grown among the bourgeoisie, and a proper classification within the ranks of the Indian bourgeoisie should be in terms of size. Broadly, three sections have come into existence during
