Meant to write "... in bankruptcy court, so far." or something similar.
It's mathematically impossible for Chicago and Baltimore and a couple others not to join Detroit in the near future in bankruptcy court. I donno about the finances of Providence RI.
I'm only aware of one tech company in Detroit which is a place that makes what amounts to a small Xylinx FPGA dev board on a DIP-64 PCB so it just plugs into a circuit board or breadboard. I own one and haven't used it much but so far its a good product. But its the only tech company I'm aware of based in Detroit. There may be others who spend even less on advertising, donno. Cool as that place may be, I don't think it makes up for the collapse of auto industry employment and lack of mobility. Most of the unemployed people in Detroit originally came from the South because there were no jobs in the South, but there were jobs in Detroit. The "real problem" is there's no where better to go than Detroit for those people. If they had jobs in Minneapolis, there wouldn't be a problem with unemployment in Detroit, but there are no jobs, anywhere, for anyone not in tech, so, they sit, expensively, in Detroit.
