In this age, people are used to modern amenities and facilities. To develop a holy site which is not within easy access would bring in more visitors/tourists/pilgrims and thus more cash flow to the government, in tourist dollars. Yes there will be more jobs and the locals will benefit from it. The economy improves and with it comes better education, living standards, better income.
With the influx of tourists, comes the issue of over crowding if the development is not properly planned. Then, what about pollution?
Development of a holy site is good but the government must bear in mind to preserve and maintain the originality of the site.
