There's a lot said about Canada and the US eventually becoming 1st tier nations via good professional set-ups. I don't think this is a pipe-dream but it's very ambitious.
I'd MUCH rather see Pro 12 teams in Georgia and Romania, these guys are already competitive 2nd tier nations and their proximity to Europe makes this possible.
Would they be able to match France's paychecks? No, but neither can Wales, England, etc. The reality is if these nations could get a Pro 12 team with 25 locals (plus some Russians, and aging players from the SH) and then have another 20 or so kicking around in the Top 14 then we'd see them becoming Tier 1 in a matter of years.
I don't understand why this isn't happening, the money isn't as high in Georgia/Romania but neither is the living costs. Run them as a cheapo development side like Connacht were and the way Wales is considering running the Scarlets or Dragons.
