The Starmer thing is obviously crap but I think it’s a mistake to do a “interests of business & workers are always opposed” in response because that’s just not true and limits our thinking of the capitalist state.
A grim aspect of capitalism is that popular needs are generally satisfied through wages. This does create shared interests: workers don’t want their firm to go under, there are shared national interests in imperialism, cheap nature (etc).
A lot stems from interlinked presumptions that a) there are two uncomplicatedly constituted classes facing off against each other, b) a flattening that obfuscates differences between revolutionary & non-revolutionary situations or that can’t think the specificity of crisis
Fairly obvious example, a better furlough scheme both policy wise & in timing of announcements would have been good for the company I worked for & me (they wouldn’t have needed to make me redundant)
Given that though there were antagonistic interests (me & my colleagues getting a better payoff, defending terms & conditions of retained staff), but there’s always (except in a revolutionary crisis) an interplay of shared & antagonistic interests.
