JOHANNESBURG (Reuters) - Zimbabweans living in South Africa hope the move by the military to seize power from President Robert Mugabe will end corruption, abuse of power and economic hardships, even though uncertainty remained as to who was in charge. Zimbabwe s military seized power early on Wednesday saying it was targeting  criminals  around Mugabe, 93, who has ruled Zimbabwe since independence in 1980. Several million Zimbabweans have fled the country, mostly to South Africa, after the economy shrank by more than a third from 2000 to 2008 following the collapse of the agriculture sector. Unemployment rose to over 80 percent. Many in the diaspora said they were happy to see change back home at last.  I think it s a step in the right direction for a political situation which was now a joke,  Kevin Mpofu, 28, said.  The arrests that have happened so far are a celebration for many Zimbabweans tired of the corruption and abuse of power.  A 30-year-old Zimbabwean working as a marketing officer in South Africa who gave his name as Billy said it was  about time but it might be 20 years too late.  He worried that one strongman might follow another:  It may be hard in future to remove that person as well. We might have another 37 years ahead of us of a single person.  The main goal of the generals appears to be preventing Mugabe s wife Grace, 52, from succeeding him. The military stepped in after Mugabe sacked his presumed successor, Vice President Emerson Mnangagwa, last week. Mnangagwa s unexpected downfall followed months of sometimes vitriolic attacks by Grace Mugabe, who used national rallies organized by ZANU-PF youths to attack her party rivals.  We have suffered way too long under Mugabe, and ironically to some point Grace Mugabe is our hero. If it wasn t for her big mouth and her big ego this situation would not have happened,  said 36 year-old Mbangeni Nyathi, Johannesburg-based spokesman for Tajamuka, a pressure group calling for change in Zimbabwe.  We are not sure who is in charge but we are ready for any kind of change. Our hope is for the military to pave way for free and fair elections,  he added. Zimbabwe s economy briefly stabilized from 2010-2014 when Mugabe was forced to accept a power-sharing government with the opposition, but since then the recovery has unraveled. A chronic shortage of dollars has led to long queues outside banks and imported goods are running out. Asked if he would return to Zimbabwe if the economy was revived, Billy said:  Definitely, there is no place like home.
