what is needed for long term growth in an economy?

Question

recently i read an article in guardian,london that for long term economic growth more capital needed to be infused in the economy and increase in productivity per unit of capital and labour. my questions are: cannot growth be achieved just by putting more capital? is it necessary to increase productivity per unit of capital and labour?

Answer 1

Long term growth in an economy is based on little government interference, a friendly environment that will stimulate corporate participation, moderate taxation so capital is left in the business to increase productivity and participation from the employee to help meet the internal goals, for which he too, will benefit.
