The differences between then and now is two-fold... 1) political will, and 2) scale.
Regarding the latter, it's easy to do if you keep up and do it as it happens. It's not a huge undertaking, and it's not too disruptive to the overall economy..
Illegals do not make up a large percentage of our workforce. Contrary to what pro-illegals claim there is no significant discount on goods and services as a result of illegal alien labor.

I think what most Rep candidates are saying is that it wouldn't be doable now because we let it get too big and it would be unwieldy and unworkable
Almost every one of those people saying that want amnesty. They act as though mass round and deportation is the only solution that the anti-illegal immigration side proposes so they can pretend that can never work even though it has been done in the past that the only possible solution is amnesty. Getting illegal aliens back into their country will require different solutions.Round ups and deportation are only part of it. The following should go along with round up and deportations.
1.Crack down on the scum who hire illegals.Treat them no different than we do drug dealers and other criminals who profit from and or use their money for illegal activities.
2. In order to get any ID or driver's license you present a birth certificate(
in rare cases a non-availability birth certificate where it has been investigated that the individual was born in the US), green card, or certificate of naturalization and social security card.After that require a state issued ID or driver's license in order to the following-
-enroll yourself into school
-enroll your minor kids into school
-apply for welfare,food stamps,section 8 housing and any other tax payer assistance for yourself and or your children
-get a business license,fishing/hunting permit,building permit, license to practice law, food handlers permit, gun license(in states that require a permit to buy a gun),concealed carry permit(in states that require a license to conceal carry) or any other tax payer funded service
-open a bank account, cash a check, use a credit/debit/pre-paid card, apply for a loan,or wire money.
-rent,borrow,lease or buy property
-rent,borrow,lease or buy a motor vehicle.
-get legal documents for yourself or your children.
-get utilities
3.Mandate E-verify for every employer.
4.Repeal part of the immigration and nationality act of 1965 that allows for the chain migration of relatives other than spouse or minor children.This would virtually eliminate anchor babies.
5.Seeing how many of these people here illegally came her on a visa and let it expire we should also cut off visas to citizens of countries we have the most illegal immigration problems with until those numbers go down.
I am so tired of the silly little memes libs foment to forward their retarded agendas. Also, if we quit paying able bodied people NOT to work, those crops would get picked, toot sweet.
