That was my perception when comparing the 1970/80 with the equivalent recent times.
But that was just a subjective view. You will be very aware that during the earlier period, strikes and mass protests seemed to almost be the norm. But I did do a quick search and the evidence seems to show that there are more protests by number since the turn of the century.
OK, sorry it was my perception you were talking about protests that
actually achieved something, (I suppose I shouldn't start reading other people's posts halfway through the exchanges...mea culpa!). Obviously protests 'over time' have a better chance of success, or partial success as the number understanding the arguments or the argument itself tends to increase wider understanding.
My perception is that since the millennium, the various 'protests', in particular
on the streets type of protest seem to attract a multiplicity of protesters, of issues and ideas, and they tend to become 'carnival-like' in terms of public perception... aided of course by the (ever greedy) 24-hour/7-day week media news cycle.
Somehow the older/last century 'protests' seem more focused and 'redder in tooth and claw'... but that's probably just me and the benefits of hindsight.
