Final answer:
The rising concern for infrastructure in the airline industry is due to factors such as population growth, technological advancements, higher disposable income, and tourism growth, alongside the historical context of deregulation leading to more efficiency and jobs but also competition and safety concerns.
Step-by-step explanation:
The concern for infrastructure in the airline industry stems from the anticipated doubling of demand for aviation products and services every 50 years. This increase in demand can be attributed to several factors: the growing population and urbanization, which create more potential fliers; advancements in technology that make air travel more accessible and efficient; a rise in disposable income allowing more individuals the financial means to fly; and the growing tourism industry, which increases the desire to travel. All these factors challenge the current infrastructure, necessitating upgrades and expansions to meet future demand while maintaining safety and efficiency.
Deregulation has led to greater competition in the airline industry, resulting in more cost-effective and efficient travel options, contributing to a significant increase in air passengers. This has not only reduced airfares but also increased the number of jobs in the industry. However, ongoing safety and competition concerns must be addressed as the infrastructure evolves to accommodate this growth.
