Makes sense on several fronts.
The past economic crisis has left many unemployed males in prime working years of their lives. The areas where they were once employed have either downsized, moved off shore and or otherwise caused a reduction or even elimination of former jobs, so they must find something else.
Until recently male college graduates out numbered women in the United States thus within certain generations you are likely to find a good number of unemployed/under-employed men who already have four year college degrees.
For this and several other reasons including various federal and or state programs for the unemployed make attending an ABSN program very attractive for males. Oh and you can also add the reduced stigma attached to *male nurses* as being either gay or somehow short changed in the masculine department . Wages in many areas of the USA for new grad BSN nurses aren't to shabby either (>$73K on average in the NYC area), which is another plus.
