And other paces dont? Almost every country has severe issues related to all the above. In the US, we have litigation everywhere, you fall and slip in a supermarket? Lawsuit! You tripped over a pothole? Lawsuit! Heck, lawyers advertise to do this...
Part of this is we don't have a social safety net, like universal health insurance.
>you fall and slip in a supermarket? Lawsuit!
You fall and slip in a supermarket, due to a careless employee and now you owe hundred of thousands in medical bills. Some executive somewhere realized it was easier to extract that cash from a corporation than putting some person deep in debt.

You get hurt in a big way, your insurer will make you sue.
