Listen - as long as we have geopolitical instability and the opportunity for a better life in the US what there will be illegal immigration. It would be naive to pretend otherwise, so we need policies to address that.

So the question really should be:

1. Will this law incentives more people to participate in illegal immigration
2. Does the greater good of this law outweigh any of the possible downsides

On point 1 above - I really don't think making illegal immigrants get licenses and pay for insurance is somehow going to incentivize more people to immigrant illegally.

And for point 2 above - resoundingly yes. Primarily through the general public safety benefit which will improve quality life for legal MA residents.
