That’s an exaggeration. The US has a better safety net than a lot of countries with much less gun death and violence. Education could better for a rich country, but is not bad. I am all for locking fewer people up, but that’s not the reason there’s gun violence.
This is always the argument against improving anything in the US. “We’re too special!” It’s just not true. Background checks, wait times, permit requirements, concealed carry restrictions, domestic violence restrictions, etc. These have all been empirically shown to reduce gun deaths in the US.
