Under capitalism, there is no tax-financed, government regulated safety net, so there is nothing for immigrants to take advantage of; those in need will find plenty of support among the many voluntary safety nets that we discussed earlier. But most likely the need will be limited, because a country without a welfare statist safety net primarily attracts immigrants who want a job, not a handout. Such immigrants want their individual rights protected and to otherwise be left alone to make a life for themselves in their adopted country of choice, interacting with others to mutual benefit.
