Why are we like this in the west?

If a goverment is not like ours, a capitalist democracy, we seem to say they are opressed or evil. If a leader is not elected, I will use Mao as a example, in my eyes, he forced his way into power with a army of supporters and made China a more modern and industrius place. To others he made it a Communist dictatorship with no freedoms, so why do we view other goverments like this?
