legal immigrants are more appealing to the government because they pay taxes and become normal citizens that the government can make money off of just like everyone else. illegals, on the other hand, give nothing to the community, but just take jobs that legal citizens should have. therefore, illegal immigrants are like parasites because they come and take what they can, for as long as they can, at the expense of the community, until they either use up the resources, or else get deported.
