That is a great question. I work in Detroit where there has been some modest growth in the downtown area with little benefit to the local population. There are not nearly enough entry level jobs to satisfy demand and the public school system is in disgraceful shape. To give a little back to the community would only require a small fraction of the cost of development - entry level job opportunities, funding for educational resources and safer schools, access to affordable and nutritious food. Sadly, the reverse is encouraged - local leaders would prefer the poor were washed away like street litter. It is shameful and inhumane. The angry tone of the article justifies it - "these people" are bad and deserve it.
