Final answer:
The hospitality industry increasingly requires specialized training due to the demand for professional services, particularly in healthcare and elder care. Jobs like nurse's aides and assisted-living management positions signify this need for specialization. Service roles vary in training and wage potential, but overall, the trend is towards more specialized knowledge.
Step-by-step explanation:
The hospitality industry today indeed calls for persons with highly specialized training. The jobs mentioned, such as those in the health field and elder care system signify significant growth and require specialized training and education. These positions range from associate-level positions like nurse's aides to management-level positions at assisted-living facilities. The increasing needs of the aging baby boomer generation amplify the demand for specialized services and trained professionals in the healthcare and hospitality sector.
Conversely, unskilled labor in sectors such as farming are witnessing a decline. Service jobs in the tertiary sector, represented in the image of a waitress at a hotel, may vary widely in terms of training required and wage potential. The growing complexity of jobs within the hospitality industry necessitates a higher level of specialization and demonstrates that merely basic education may no longer be sufficient for many emerging roles.
Overall, while there may still be opportunities for lower skilled positions, the trend in the hospitality industry is towards jobs which demand higher levels of specialized training to support the evolving needs and services required by the public. A clear example is the transition from a construction worker to a fast-food restaurant worker, which highlights the shift towards service-oriented roles that might not require specialization but do benefit from specific training.
