Why Did Scotland Become Independent?

It is argued that Scotland could be a prosperous country on its own right. If Scotland became independent, it would be one of the wealthiest countries; as a result, its economy would increase, which would afford “welfare spending” including pensions and debts (Scottish Independence). Although the economy would increase if Scotland attained its independence, there is a debate that the economy would not be stable. That is because the Scottish would depend more the country’s oil and gas, which may run out as Sir Ian Wood warned (McKay).
