The EITC is a great tool for efficient re-distribution of resources to working Americans on the lower rungs of the economic ladder. It's efficient and we can turn the knobs to adjust it as necessary to fit our needs, such as not being as generous to teenagers that live in an existing household (something that minimum wage increases do not account for).
The only downside to the EITC is the once-a-year aspect to the distribution. It would probably be wise for us to develop a more reliable distribution of the money so that it provides a more even boost to the worker's regular paycheck.
