Buhari approves an exchange rate of N160 to $1

The president has approved an exchange rate of 160 naira for christian pilgrims in other to help them in reducing their expenses.But people from opposition parties have come up saying that 140 million christians went for pilgrimage last year and the president has decided to cut dollar exchange for them meaning the government will incure a debt of $68 millon in subsidizing dollar.But what I think is if the government can afford the subsidy why can't he go ahead is the government not meant for the people
