Ineffective Democracy

Could one of the reasons for a substantial number of Scots wanting to split from the UK be that we have an ineffective democracy? On several occasions I've seen and heard interviews with Scots who point out that in the last election they only returned one Conservative MP yet are now lead by a Conservative Prime Minister (in a Conservative/Liberal Democrat coalition).
Would the earlier introduction of new powers for Scotland's parliament have avoided the devolution referendum? It may have done.
Would Direct Democracy, like Switzerland, have empowered Scots? Probably. The Swiss have long prospered with a system of Cantons speaking different languages and doing local government.
Seen in this light, the possible break up of the UK can be seen as an indictment of our political system by the Unionist side. Too little, too late. Too central, too out of touch.
