I'd opt for the second approach. We can amend the bill when we start implementing it.
We don't have time to wait for the bill to be perfect. We've been studying it for seven years, and we could continue doing so for a very long time. I don't want the next generation to be testifying here in 10 years.
As I said, it's important to acknowledge that the people currently on the ground are being assimilated as we wait to make decisions.
It's good to have a plan for growing and catching up, but we have to assist those in this situation. Telling people who are being assimilated now that others will replace them later on isn't an appropriate answer.
The time to act is now.
