If the rebuttal is "yeah but advancements improve the economy" -- The private sector can fund projects which are opportunities with an economic basis, they can take the risk and they can see if it is profitable in the market (ie beneficial)
If the rebuttal is "How will America stay competitive?" We cant seem to keep trade secrets anyways. [1]

Edit: Also the 4 years at a time thing is probably a better choice too, because it makes them less twitchy politically. You get your 4 years, regardless of who's team is in office. This should be a win regardless of your affiliation.
2) How do you feel about the money going to ICE?
Not sure why it matters what I feel about ICE, besides an attempt to categorize me or my affiliations. However, in general I believe the US has a large amount of very silly self inflicted wounds, a terrible immigration policy has lead to a situation where people only/primarily get in illegally, and then those people have to make compromising choices based on their legality. Attempting to reset the playing field is noble, but fixing the path to legality would have been nobler. A big chunk of it is a waste of money in an attempt to chase the holy grail in America... "Jobs".
