If the government decided that each family needs a minimum income of $25,000 and promised to make up the difference between whatever a family earned and $25,000, which of the following is correct?

a. This program would reduce the incentive to work to earn any wage up to $25,000.
b. The government is effectively taxing every dollar earned up to $25,000 at a rate of 100%.
c. If workers are discouraged from working due to this program, they will miss any on-the-job training that would have otherwise occurred, limiting their ability to improve their skills.
d. All of the above are correct.

In the case when the government decided that each kind of family required atleast income i.e. $25,000 so it would decrease the work incentive for earning till to $25,000 also it should be taxed by the government. In addition to this, in the case when the workers are discouraged so they miss on the job training and limits their capability for improving out their skills

So as per the given scenario, the option d is correct
