If you physically can't sleep because you live too close to plane/bus/road noise, then perhaps you might want to consider moving to where there is none of the above. However, if you insist on living in a crowded metro area, then you have nothing to complain about, because you chose your living conditions. If you say you can't live elsewhere because there's no work, well, you selected that career. If you like your standard of living, there's plenty of people who like their standard of living and they don't deal with plane/bus/road noise. Lots of people live in the 'burbs or further out.

It's your choice. Complaining that you're stuck when you chose your life isn't my issue, it's yours.
