Austerity helps perpetrators.
Of course the perpetrator is the one who ultimately chooses to commit VAWG, but austerity provides them with the opportunity to do it and do it more often. Many services have had funding cuts, there's an affordable housing shortage, child support system isn't as effective as it should be.
The only way to address the issue and to keep women and children safe is by funding good public services, more social housing, supportive benefits system, and improved child support system.
