In the US, there's very little social safety net to catch you. If you get sick before the startup is big enough, it means personal bankruptcy - and no medical treatment. Missing revenue targets can mean missing student loan payments, missing rent, etc. There's real risk you'll end up homeless in the end.
In Sweden, you might end up poor, but the poor are still taken care of. You get your medical treatment, the state pays your rent, and you are guaranteed enough income to buy groceries.
