Why do we need economic growth?

Most things don’t grow forever. If a person grew at the same rate for his whole life, he’d become gigantic. Yet most economists are united around the idea that the economy needs to grow, always. And at a high rate, for the good of the country and its people.

• Economic growth is the increase in the goods and services produced by an economy, typically a nation, over a long period of time. It is measured as percentage increase in real gross domestic product (GDP) which is gross domestic product (GDP) adjusted for inflation. The economic growth every year is essential to a country’s stability and prosperity. But some economists argue that it makes more sense to focus on measures of well-being than growth.
• Maximizing growth doesn’t necessarily help people, but also that rapid growth can itself come at a cost, such as when the pursuit of growth is used to push through policies that are expected increase the GDP but may have negative consequences for millions.The pursuit of growth can be quite dangerous. The welfare of a nation can scarcely be inferred from a measurement of national income.
• For a developing economy where the basic need isn’t met and growth is necessary for more food. Economic growth in a developing economy can go a long way to improving living standards. When people are living in poverty, they experience a deprivation of basic human needs, such as food, shelter, education, basic health care. Economic growth can enable many of these basic needs to be met and this economic growth can radically increase living standards among those countries.
• It's an election winner. Politicians see growth as very important. Elections are won or lost on the state of the economy. Look what happens if growth disappears and recession looms. People get very concerned about falling incomes and rising unemployment. 
• If poverty is to be relieved and the rich are not to be made poorer, then growth is necessary. Making the poor richer is not easy and there are many political obstacles in the way. But at least growth makes it easier.
• When real incomes are already quite high, economic growth can have a marginal impact on living standards. There is a strong diminishing marginal utility to extra income. 
• Economic growth is driven by technological improvements, which reduce the costs of production and enable more to be produced. This technological progress in many ways feels an inevitability. How could you stop this technological progress? Technological improvements have particularly improved the productivity of agriculture and manufacturing. This means we can support ourselves with a smaller % of the workforce on agriculture and manufacturing. Many of new jobs are in service sector.
• In theory, economic growth should enable people to work less, enjoy more leisure time and would enable to retire earlier, if they are able and willing.
• Increased GDP offers the potential for higher living standards but certainly doesn’t guarantee it because of uneven distribution and how it is used. GDP measures activity in the economy, but there’s no way to know whether that activity is actually good for society. The BP oil-rig explosion, which killed 11, and the subsequent spill, which leaked 3 million barrels of oil into the Gulf, actually lifted GDP because of the amount of money spent cleaning it up.
• Economists often say that without growth it will be impossible to address income inequality. But even with growth, there’s no guarantee that inequality will decrease. The economy’s current trajectory is of increasing inequality. Economic growth leads to the depletion of resources - a problem that's likely to get worse as world population and world consumption grows.
• One of the biggest sources of rising expenditure in western economies is health care. There are simply more things that can be treated. Also, there is the irony of having to treat diseases of affluence (such as obesity, heart attacks, cancer etc).
• Economic growth will not solve the fundamental problems of human psychology / behaviour. It can increase sense of inequality. Growth will not reduce the incentives to cheat and steal. It does not make people more charitable and good-natured.
• Environmental problems facing humanity, economic growth could exacerbate these issues and reduce living standards.
• Some of the most content people in the history of the world got by on a lot less. Some saints have argued they were much happier when they forsook their wealth.
• Rather than worrying about increasing real GDP, we could spend time promoting greater social harmony.
• The point is that life is a struggle for most people in developed economies, and technology and increased efficiency has not done much to fix that over the last 40 years. No doubt there are a few that have enjoyed increased leisure time, but at the expense of the masses.

Do we need economic growth? Not really. But, if managed well, it doesn’t have to do any harm and gives the potential to make improvements in our material well-being. Needless to say, economic growth is far from the panacea to make society better. It is a neutral component of human well-being. There’s nothing wrong with targeting economic growth as long as you are aware of its imitations. Governments and society need to be judged on so much more than simply whether their economies are growing.

wealthier people serve poorer people as well.

For India with large number of unemployed youth, economic growth is the only way to create enough jobs and security. The present phenomenon of jobless growth is unsustainable. The current trends of economic growth are also associated with increased pollution, over exploitation of non-replenishable natural resources, destruction of ecology etc is a destructive growth. Additional wealth created is grabbed by top 10% wealthiest people. The disparity between rich and poor is widening. This kind of growth is absurd. In an ideally developed world all people should be equal, even though perfection is unachievable. We need to grow to accommodate ever rising population.
