I don't think you understand any of this.
The Tories had choices, every government does- Where do you raise money from? Where do you invest it?
The Tories do not raise money - they want to keep taxes as low as possible for the most wealthy. What they do is reduce spending on public services. They call it 'small state intervention'. They mean not providing universal healthcare, investing in high quality education, not having services that they recognise need to be centrally maintained like energy, water, transport. Instead they leave people to fend for themselves- which affects the poorest much more than the wealthy. If Mr Sunak or his family require healthcare, or cancer treatment or dentistry, they can pay for it without blinking an eye and it will be on tap very quickly. If someone earning £100,000 a year requires it, they can afford health insurance that means they too have access to that service. For the vast majority however, that is not the case and they are the ones who suffer from the NHS underfunding. That suffering is life-changing.
They prefer not to invest in nationalised industries- there are none left so I am not sure which you are referring to when you say 'the already nationalised ones aren't working'. They used to be: the phone system, Royal Mail, British Gas, Electricity, Water, British Rail etc. They are all disaster zones now - they were privatised so that various Tory governments reduced the burden on the State for that provision and allowed their capitalist cronies to make billions for themselves asset stripping them, not maintaining infrastructure and increasing bills exponentially with few limits on what they charge us. We now have an approaching catastrophe with water and energy and no plans from the companies involved to resolve any of it apart from raising prices.
You raise monies in several way - taxation is one, allowing private investment is another. The Tories prefer private investment- the responsibility is no longer the government's and their pals make whopping profits and they allow voters to keep more of their earnings (except it NEVER works out that way, only for the already very rich).
The richest should pay more of the tax burden. Everyone should pay something more but the richest should shoulder more of the burden.
If you invest in people by paying them more, they pay back more in taxation, they spend their extra money in your economy. If you don't, they pay smaller taxes or none at all if they are unemployed, and have nothing to spend so the economy shrinks and businesses collapse.
If you invest in health and education, you produce a population that is healthy, able to work and skilled, that has educational confidence, that are entrepreneurial and creative risk takers, scientists, technologists, people who want to contribute and give back to create a big society. If you don't, you produce a population that is unhealthy, can't work and is unskilled- there are no people to do the required skilled jobs, to build businesses, to be the social contributors and train as Drs, dentists, teachers, nurses. People struggle to look after themselves.
An example of Tory cynicism sold to the British working classes by Mrs That her as 'giving them an opportunity' was the selling of council houses. The Tory government was concerned about how much social housing was costing- there was an aging stock of council housing and they were worried about cost of repairs but more so of replacement. Mrs Thatcher sold it off through 'Right to Buy'. Not only did she sell it off- often to unwitting council tenants who could not afford to buy any other way but were actually paying relative peanuts often for houses that were in need of significant investment and repair- but she prevented councils using the money raised to build new council houses- because she did not want the State to have the responsibility fir social housing. Any new housing councils funded themselves was subject to;Right to Buy' legislation so why would they keep building if they could be forced into selling it at huge discounts after 4 years and finding themselves without the housing stock?
The knock-on effect was....wait for it.....a massive expansion in private landlords, buying up housing that they then rented out to tenants who could no longer find a council house to rent and .......charging them vastly inflated rents in comparison to council rents because now it was a privatised business run by capitalist landlords who were in it to make fortunes. Thete were people who owned thousands of properties around the country, whose mortgages on those properties were being paid off by tenants who coukdn't afford their own home and could not get a council home and, in addition, were funding the living expenses and lifestyles of landlords. It continues today.
Adult social care is another example.
It's how the Tories work- they don't give a stuff about small people, only about offering opportunities to the rich to exploit them. They don't want to be a government that takes responsibility for building a fair society for everyone.
