Sure it impacts my job. I work in the market data business, and we're the ones supplying the data used to make trades to a lot of brokers and banks.
There is a chance (given historical record) that governments will step in and require that part or all of that data be regulated or even supplied free of charge in the future.
That would affect us massively.
But indeed, the average person won't be affected unless it's he works for one of the mortgage firms or hedgefunds that are now in trouble because of bad deals they funded with loans.
