Well, I'm kind of on your side, but comparisons to a time when riders had to weld their own fork together on the roadside, don't seem very meaningful to me either.
I just had a quick look through the GC after WWII, although maybe I should have started in the 80s, because the national team era of course was different also, but notable team results are:
1949: Italy 1,2
1952: Italy 1, 4, 6, 9
1953: France 1, 7, 8, 9
1955: France 1, 5, 6, 10
1960: Italy 1, 2, 7, 10
1962: Saint-Raphael: 1, 5
1963: Saint-Raphael: 1, 4
1967: France 1, 6, 9
1979: Renault: 1, 4
1984: Renault: 1, 3
1985: La Vie Claire: 1,2
1986: La Vie Claire: 1, 2, 4, 7 (probably most dominant team ever from the result)
1989: PDM: 4, 7, 8, 9
1992: Carrera: 2, 8, 9
1995: ONCE: 2, 4, 6
1996: Telekom 1,2 and Festina 3, 4
1998: Cofidis 3, 4, 7
2002: ONCE 2, 5, 6 (#1 DSQ)
2004: T-Mobile 2, 4 (#1 DSQ)
2007: Discovery 1, *3 (Leipheimer DSQ), 8
2008: Astana 1, *3 (Armstrong DSQ), 5
2011: Leopard 2, 3
2012: Sky 1,2
2015: Movistar 2, 3
There's a bunch more where 2 or 3 riders from one team made the top10 but didn't win, I didn't copy all of them.
Just going by the GC this years Tour de France doesn't show extraordinary team strength, but that ist clearly an incomplete analysis, because for example US Postal/Discovery doesn't show up here.
