I think it will be hard to recommend depending on your exact positions on these.
I think it will be difficult to recommend a place with low taxes and robust safety net. Generally the taxes are what Pay for a safety net.
On that note, the US could be an option (southern states) for you since the taxes tend to be lower than other developed nations. The safety net is fairly robust, but only applicable in many cases if you're destitute. The caveat is that politics suck here, but they suck basically everywhere.
