The true measure of the physical barrier is not costs, but effectiveness. If we can reduce the number of invaders, the costs are well worth it. What are illegals costing us in terms of our social welfare, educational, penal, and medical systems or the additional infrastructure to support them?
"How much do the 500,000 to 1 million illegals cost us a year?"

This study is one of the first to estimate the total impact of illegal immigration on the federal budget. Most previous studies have focused on the state and local level and have examined only costs or tax payments, but not both. Based on Census Bureau data, this study finds that, when all taxes paid (direct and indirect) and all costs are considered, illegal households created a net fiscal deficit at the federal level of more than $10 billion in 2002. We also estimate that, if there was an amnesty for illegal aliens, the net fiscal deficit would grow to nearly $29 billion.
Among the findings:
Households headed by illegal aliens imposed more than $26.3 billion in costs on the federal government in 2002 and paid only $16 billion in taxes, creating a net fiscal deficit of almost $10.4 billion, or $2,700 per illegal household.
