The basic rule of condensation is that if there's dew on the grass outside your tent, there will be condensation on and in your tent (even if it's a tarp rigged to be open). You'll also get condensation if there's no dew, but it's warmer inside the tent than outside. That's all basic physics, and there's nothing that can be done about it (in practical terms).
American tents are designed for use where dew isn't common, and with lots of mesh on the inner and big gaps under the edges of the outer to reduce in-tent warming. You therefore generally get condensation in them less often, but on the other hand you may need more warm clothing and/or a warmer sleeping bag, and you may get rain blowing in under the outer edges.
European (or at least British and Scandinavian) tents are designed for use where warmth inside is more viewed as an advantage than a drawback, and wind-driven rain is relatively common. The downside is more frequent condensation.
That the UK is on the same latitude as Labrador or Edmonton, and that the US on the same as the Mediterranean, probably has a lot to do with the differing views on what makes a good tent.
Small tents warm up more easily than larger tents, so generally get more condensation.
One thing you may be able to do to reduce or eliminate condensation is to camp where you don't get dew, like under or immediately adjacent to trees. This does have it's own drawbacks though - drips all night after rain, sap drips in aphid season, or the chance of a branch falling off the tree and squashing you.
