Totally agreed.
But the nice thing about the newspaper (The Economist refers to itself as a newspaper, not a magazine) is that they provide pure opinion journalism and as a reader you know exactly where they are coming from.
While I agree a lot with the publication (for example: they argued to liberalize drugs, or advocated gay marriage literally decades before it was chic). I encounter my share of (what I lovingly refer to as) full-of-shit opinions, with which I wholeheartedly disagree.
Overall, though, it's one of the last remaining publications, on which I put a certain amount of trust because they usually know what they're writing about and even on the subjects on which I (partially vehemently) disagree it's always an interesting read.
Because they argue their position intelligently and competently. It won't make me a believer, but it's useful and interesting to get the counterpoint from a reputable and trustworthy publication and sometimes get your dogmas slightly shaken in the process.
