The Adam smith institute is a right wing free market think tank with likely very questionable donors. wiki It likely doesn’t really do research but takes sources that support their preexisting believes and retells them.
Certainly it was at least very hard to make the capitalist exploitation of the worker so all encompassing before the invention of the mechanical watch (Although there was likely a ton of housework and the general situation was garbage what with feudal lords and all that) . It then likely exploded with the industrial revolution and at least in places where the working class managed to emancipate themselves got somewhat cut back. Now especially for countries outside of the west and increasingly also the US and parts of EU it’s likely getting worse, especially with multi employment and precarious employment(gig work, semi self employment, 0h contracts, mechanical turk …).
Generally i feel work where you or your peers get to keep the total output of your work isn’t really a problem, it’s a problem when your work gets appropriated into this terrible machine and as a result you are alienated from the work.
