The major benefit of locating in Jersey City is people. And, access to people.
People comprise markets and people comprise labor.
As such, it is the largest single market in the country and businesses with direct access to this market will not fail for lack of customers. No matter what position a business is trying to fill, there are going to be scores of qualified applicants available. Another benefit to locating in Jersey City is access to the largest seaport in the North Atlantic. If your business depends on access to world markets, Jersey City provides a ringside seat from which to watch and play the global marketplace. It doesn't matter which side of the Hudson you're on to benefit, as long as you're on the Hudson.
