I think the pundits are too pessimistic as usual. I believe that 4% annual growth for a decade and more is possible. The economy would get a boost if the governments (federal & states) cut taxes, curb bureaucracy & ease immigration (johnhcochrane). America also could follow the European role model and privatize state owned enterprises like airports, harbors, mail & railways (Amtrak). The proceeds could be used to invest into the infrastructure (streets, railways) which is in a lamentable condition. Privatization and a better infrastructure could lift the American productivity and foster growth.
But the main point for my optimism is independent from a political change. I think the US economy - and the rest of the world - is benefitting from a high-tech revolution. There is a deluge of technological innovations, creating a lot of positive tailwinds for the global economy in the coming years (driveby).
We are seeing rapid advances in:
- Robotics: Companies are using more and more robots to reduce costs and to respond more flexible to the demands of their customers. For instance robots are welding car parts together and are varnishing them & Amazon is using robotic systems in her gigantic fulfillment centers. The automatization process leads to cheaper & better products.
- Self-driving cars & trucks will reduce the number of accidents and lower costs of transportation, which leads to cheaper consumer goods. Because they are efficient they waste less fossile energy - good for the environment.
- 3D printing: Software controlled machines are literally "printing" parts of other machines and devices by using computational power, lasers and basic powdered metals and plastics. Soon companies & persons can produce almost anything exactly bespoked for individual tastes with low costs.
- Nanotechnology: The creation of new materials, built at the atomic level, could revolutionize everything from chemistry to aeronautics, like creating new medicines, new fabrics and building material. For instance scientists are working on a new material which is much stronger & lighter than steel (economist).
- Biotechnology: Companies and university scientists develop new vaccines and cures by adapting or exploiting processes found in living organisms which could lead to a longer & more healthful life for all of us. Altering plants by genetic engineering makes them more resistent against pests and more tolerant of temperature changes and draughts. Food gets more affordable and could be enhanced with vaccines against cancers and other diseases.
- Health technology: Sophisticated machines improve the quality of healthcare through earlier diagnosis, less invasive treatment options and reductions in hospital stays and rehabilitation times. So these technologies improve life quality and productivity.
- Internet of Things: Devices like thermostats, TVs, refrigerators, household appliances are or will be soon connected to the world wide web which will make our life easier and create newmarkets for a lot of companies. Smart watches for instance can be used for 24/7 medical observation and health monitoring to prevent heart attacks and to discover other medical problems.
- Cloud computing: Amazon.com, IBM, Apple, Google and other companies offer data storage and processing either for free or for low fees, giving everybody access to a network of supercomputers. Companies & persons can process and store huge amounts of data without spending much money for own data centers.
Falling Information Costs
In general the Internet - including the "cloud" - increases the flow of information and reduces the cost of data. Data can be gained, processed and stored faster and cheaper. New ideas can spread faster, encouraging discoveries and inventions and boost the technological progress. Falling information costs are creating more markets and are expanding existing ones.
Restaurants, shops, movie theaters and a lot of other companies are gaining more customers because they can be more easily found and can advertise better for their products & services. Applications and recommendations from friends or unknown reviewers on Amazon.com, Facebook and other websites can gain interest for many products & companies which would have stayed unknown without the Internet. I believe that the falling information costs foster economic growth because they lift the productivity of companies & persons.
Examples: Internet based travel networks like Airbnb - a website for people to rent out lodging - give people additional income by temporarily leasing or sharing their flats. Their customers can reduce costs for vacations or business travels which fosters tourism. Uber, a transportation network company whose mobile apps connect passengers with drivers of vehicles for hire and ride-sharing services, enables car owners to earn an additional income, their customers reduce their travel costs. Big data processing companies like Hopper are helping people to find cheap flights (hoppertravel). I reckon that in the coming years many other new companies will appear using the Internet to create new industries and markets.
Many of these technological adavances are working together, amplifying their impulse. These innovations are lifting the productivity of the economy significantly and are creating new markets & incomes. And it looks like that the technological progress is accelerating. Almost daily new products and companies with interesting business ideas appear. All these developments are adding up and accelerate the economic growth rate.
