I think that's the point, to use Suffolk Downs to jumpstart the area in terms of density. It's close enough in that it should be much denser and taller.
The scars of Pruitt Igoe and Cabrini Green and their kin cut very deep in the psyche of developers and city planners, and have never healed. Essentially, these projects -- with 3,000, 4,000 units in tall buildings proximate to each other -- were warehousing people who had no ownership stake. Once poverty, unemployment, and crime became their defining features, the residents wanted to live anywhere but.
Using a primitive housing affordability calculator on money.com, and using $150,000 as my annual income, and making a down payment of $50,000, the calculator said I could afford a condo/house selling for $822,000.
The median household income in Boston in 2017-18 was $67,000. As the value for Boston is probably skewed by the large student population, for comparison, the median household income for Brookline is $111,000; for Quincy, $72,000. Again using the calculator, if my annual income is $72,000, and I put $20,000 down, I can afford a condo selling for $420,000.
The chart on the link below gives the range of condo prices by square foot by Boston neighborhood in May 2019.

For the Financial District, which I would equate with 'downtown' (and where a poster has proposed building tall, residential towers), the price range is nearly $900 a square foot to $1,775 a square foot. If I was making $150,000, and put $50,000 down, I couldn't afford a 1,000 sq ft condo at the very lowest end of the price range in 'downtown'.
