Tories don't mind that fptp is bad for the country

First past the post is favourable to no one but the party of the centre-left (the Labour party). This is because individualists and liberals are disinclined to vote for a collectivist mainstream party... which is what is required of them under fptp. If under fptp we do not vote tactically (for a collectivist party) then our vote is wasted. So collectivists are rewarded with this system. Clearly this is not a problem for the socialist Labour party but we might imagine that a liberal centre-right party would find this objectionable. Since the Tory party do not object to first past the post we can deduce that they are more concerned with the narrow aspirations of their party than they are for their country. Tory support for fptp shows they place less importance on their country than they do their party. They put party before country. The fact that fptp is favourable for Labour and that the Tories want to keep it means that the system is bad for the country.
