We never had 'pure capitalism' in this country; certainly it is indeed 'capitalism for the many' such as disabled people who are subjected to humiliating and degrading 'fitness to work tests', etc but we have always had the government going out of their way to intervene on behalf of or bail out specific 'friends' e.g.:
- The banking bailouts of 2008
- Farming subsidies
- 'Golden shares' over 'strategic' industry e.g. the nuclear and arms industries https://www.dentons.com/en/insights/articles/2016/november/24/new-barriers-to-foreign-investment-in-uk-strategic-infrastructure
So for me the real question is to what extent the system will be shaken up.
The antonym of 'capitalism' is not necessarily 'socialism'. During my last degree I spent a lot of time studying the Republic of Korea. In the 1950s Korea was a destitute agrarian country in which the majority of people scraped a living farming dirt in squalid living conditions with no industry. By 2020 it is a world leader in electronics, shipwrighting and much else. This happened within a capitalist system but with a heavy handed, indeed draconian, government run by military generals. https://en.wikipedia.org/wiki/Miracle_on_the_Han_River
Basically the generals oversaw what we would broadly term a capitalist system but with strong-arm regulation from the central government. If the corporates didn't live up to their promises of 'creating development', they would be for it.
This is not to praise Park at all. His regime was uncompromisingly brutal, neglectful to the country's worst-off, and the legacy continues in Korea having some of the worst health and safety performance in the "developed world".
My expectation is that you won't see Tories nationalising the means of production and exchange. But they might take a leaf out of Park's book. To be honest they pioneered protectionist interventions in the economy long before karl marx https://en.wikipedia.org/wiki/Corn_Laws
