What was one economic problem the united states was suffering from when john f. kennedy became president?

High rates of unemployment were at 5.6 when john f. kennedy was inaugurated president amidst a recession recovering not very much but still high, around the early 60's. and yet unemployment still effects the economy greatly. elite daily states that "With one person losing his job, there is one less person that will pay state and federal income taxes, one less person that will pay additional sales tax revenue as a laid off worker will instantly cut back on their non-necessary spending due to less disposable income and worry about future financial security."

so this can obviously mean ripples in economic unemployment rates are not a good thing. and as jfk was becoming president, this problem was being faced in the united states. 

-hope this helps!
