This is commonplace throughout Europe.  We have high tax rates that enable a high quality of welfare provision.  This extends to free or low cost medical and dental care,  housing,  and cost of living benefits. 

The answer to why is because these societies have decided that the expense of helping people through rough patches is worth it in the long term. It can help reduce crime,  keep people out of worse poverty,  which saves health costs further down the line.  Or they just support it on moral grounds.  Or a mix and match combination of factors.
