Median wrongful death payout is 2.2 million. So for 2,000 people thats about 4.4 Billion.
I know what you're thinking....A wall! 4.4 Billion honestly wouldn't even pay for the maintenance on a full wall, let alone building it. Keep in mind though-the wall wouldn't be 100% effective. 1/2 of them are visa overstays. So the wall would only address the other half.
The right wing Cato institute has a good discussion of effectiveness and cost here:

Bottom line? 4.4 billion for 2,000 deaths, and no its not Wall money. Thats even before we address the value we often get from them working here.
