I don't know why you're saying they shouldn't vote based on "how much money they can get". Money is a big part of every referendum (£350 million to the NHS or
this lovely piece) or any election (tax cuts etc). Everybody is in it for themselves and when it came to the EU referendum, I would assume they thought they'd be better off financially or will soon be. The vast majority of people don't give a stuff about identity or basically anyone else outside their own family, they just want the best for themselves. Are they wrong for wanting that? No. Are they often mislead? Almost certainly.
More specifically to the thread, it's no surprise she's pushing for this. As far as I have seen it, the leaders of the SNP will jump at any opportunity for independence and in my opinion is just an attempt at a power grab. They're a nasty populist party as far as I am concerned who simply want to seize it for themselves. That's not to say I believe those who want independent are like that, as that's you can't generalise like that in the same way you can't generalise all Brexiters to be racist. However, I will say that you probably could generalise and say most of them are uneducated on the subject for any referendum.
I hope May gives the power of "Brexit" to Parliament. I hope Parliament reject it. I hope this independence bill doesn't go through because of this, but I can still see them pushing for it even if no "Brexit".
On a side note, I kind of do want to see what happens. Oil was a big topic the last time around and it was probably the biggest topic they could talk about, except possibly Trident. Interesting to see where they will take it.
