There's no single easiest trade to enter, but it can be fairly easy to find work in a field that has a lot of practitioners and steady job growth. This includes jobs such as barber or cosmetologist, electrician, and industrial machinery mechanic. Each of these occupations has at least half a million practitioners distributed fairly evenly around the country, combined with steady growth projections. In other words, these jobs are relatively safe bets compared to niche occupations and those that are shrinking.
