Steve,
Looking at the current trends from the bureau of labor and statistics at
http://www.bls.gov/eag/eag.pa_philadelphia.htm it looks like manufacturing and finance jobs are leaving Philadelphia at an increasing pace. This follows with the national trends of exporting all manufacturing operations, telephone support and white collar jobs like banking, insurance, and engineering. Since Philly never really had a lot of high-tech, it is not feeling the aftermath of the dotcom failure as much. With an overabundance of hospitals, the healthcare industry will see a decline. On the other hand, construction, services, leisure and government is growing at a slow pace. Philly has a very rich history, tourist attractions and cultural opportunities. What Philly lacks, like many other cities, is solid job creation for the medium to high income bracket.
There are several opportunities here.
When watching loads of people do "Duck Tours" of Philly and revitalization of Penn's Landing and South Street, it occurred to me that Philly can really become a fun party vacation destination like New Orleans or Las Vegas. The cultural opportunities are there, it just needs to be developed a bit. I think Philly needs to leave the old rust and coal industry behind become and become a popular tourist destination.
It can become the center of attraction for Independence day in the same way that New Orleans is the center of attraction for Mardi Gras or Las Vegas is for spring break, or New York city Times Square for New Years. Afterall, the declaration of Independence was signed here. What is needed is a football-field sized plaza. Before noon, the Declaration of Independence needs to be read aloud and then at noon all the city bells should ring in another year of freedom. Bands should play all afternoon. In the evening there should be a huge laser and fireworks show. Good micro-brewed beer should flow. This should be a televised event to make Philly the place to be for the 4th of July. In the long run, this will bring more tourism to Philly. Elementary school kids should be making trips to Philly just as they make trips to Washington D.C. throughout the year.
Growing the tourism industry should create new jobs and re-vitalize downtown. I think everything should be done so that business can thrive near the new tourism area. Old, decaying buildings should be transformed into open plazas with outdoor cafes, pubs and restaurants or parks. Room should be made for small and large businesses to bring their companies near this environment. This would in turn, insure that businesses stay in Philadelphia since it would be a fun place to be.
The overabundance of hospitals, urban charm and culture in Philly can be used to lure wealthy retirees to live here. If properly developed, this could be a potential growth industry. Retirees need small townhomes near hospitals which are safe and handicap accessible and near parks. The retirees need to be able to take leisurely walks around town. Intown, there should be opportunities for shuffle board, and outdoor chess. Retirees should have ready access to communications to keep in touch with their progeny. I think it is important to draw both the elderly and young people to keep Philly, a vibrant and diverse community.
I think it is important that Philly gets its share of the global economy. If all the products are manufactured elsewhere and the customer service is handled elsewhere, then there must be coincidental opportunities for the marketing and distribution of these goods. Perhaps there is a need for an intermodal facility...
When thinking of new architecture, I would emphasize taking advantage of natural light, good insulation and energy efficiency. I think new architecture can be built so that there are brick exteriors that match the older industrial architecture. I believe that solar heating concepts can be built-in so that there is less dependence on external energy.
In my vision, I think the population will remain steady, the population a bit more elderly and the ethnic makeup will be similar.
