I like your page, but your statement is silly.
When Chicago (City Government) decided to build public housing, the politicians decided that only blacks could live there. Hispanic organizations sued the City, demanding that Hispanics be allowed to occupy public housing. The Hispanics lost the case. The Courts said "blacks only".
When Chicago decided to demolish some of the public housing, politicians (government) decided that "certain" black, public-housing residents, would be given Section 8 Vouchers. These vouchers were only good in certain towns (undoubtedly pre-arranged with the politicians in those towns).
During the building and rehabbing boom of the 90's, Chicago (government) demanded that any developer who wanted to build or rehab lofts in the city, would be required to give (free) a certain percentage of the units to black, public-housing residents. The Alderman in each ward was anointed with the task of choosing the residents - who were given free title to units that were selling for $250,000 and up.
Yes; government does often decide who will live where. Government even decides who will pay for it.
None of which makes it right.
And to focus my remark further: the federal government in particular can not dictate where who shall live where. If they do they are acting illegitimately.
