That’s what the liberals want—more centralization. And it always results in the centralized area getting more top-heavy.
The notion of what towns ought to have been created and what not to have is certainly what central planners always focus on. Ferguson was originally a railroad town dating from 1850, and judging its existence on the ill results of the expansion of St. Louis (helped along more by I-70 and I-270 more than the Wabash Railroad) does not mean it ought to be absorbed by St. Louis as Governor Nixon is insisting on.
Normally, yes that is true and may even be in this case. The problem is there are 90 townships in St Louis County with almost that many different Police Depts and Court Systems. They could use some consolidation. During the Riots, they talked about townships annexing themselves 1 or 2 miles of the major roads to raise funds. Best example of this is the massive Public Safety/Town Hall in Ferguson when the town is only 6 square miles.
