According to some, the need for stronger NLRA protections is supported by evidence of all of the following except:

A) Significantly more employees say they want representation at work than actually have it.
B) Union density rates are higher in the public sector than in the private sector.
C) Corporate fraud and misdealings that demonstrate a need to balance corporate power.
D) Union density rates in the public sector are rapidly declining.

Option D contradicts the need for stronger NLRA protections by stating that union density rates in the public sector are rapidly declining, which suggests that there may not be a need for stronger protections. The other options provide evidence to support the need for stronger NLRA protections. Option A shows that there is a significant desire for union representation that is not being met, which suggests that the current protections are insufficient. Option B demonstrates a disparity in unionization rates between the public and private sector, which may indicate that the NLRA is not effectively protecting employees in the private sector. Option C suggests that corporate power is unbalanced and that stronger protections are needed to counteract this trend.
