Yeah, great times
30% inflation - at its peak, but yes generally was higher than now.
Mass IRA bombings - Very few mainland events, in the 70's Guildford, Aldershot and Birmingham, a couple elsewhere of lesser scale.
Power cuts - related to the miners strike in '74, (see 3 day working week below).
Rubbish in the streets - one winter in 1979 and very localised. No worse than Birmingham recently in the news.
3 day working weeks - related to the miners strike in '74.
Bananas being throw at footballers. - A few incidents, football hooligans just did not get it.
Women stuck at home with the kids. Some may have been, as now, many worked (at least in the North).
Gay bashing - probably no worse than recent times, again a few notable incidents.
Any decade you can trawl for bad events. I'm with Faustus on this one. The 1970's was overall a good time and felt more friendly between people.
