They are mainstream economic practices in most of Europe. The spending plans would put the UK in about the middle of the European table, in terms of state spending as share of GDP - just below France, IIRC. They have the support of a great many mainstream economists. Meanwhile there's a consensus amongst mainstream economists that the Conservative Party's austerity program was and is totally bats__t. Have a look:
'Labour has received the firm backing of 163 prominent economists who say the party understands the nation’s deep-seated problems and has devised a “serious programme” for dealing with them.
In a letter
published in the Financial Times, the group said Labour’s plans to invest in homes, schools and infrastructure make “basic economic sense”, partly because borrowing costs are at a historic low.
They called for a Labour government to urgently reform Britain’s economy which has, for too long, prioritised
consumption over investment, short-term financial returns over long-term innovation, rising asset values over rising wages, and deficit reduction over the quality of public services.
The group, which includes professor
David Blanchflower, a former member of the Bank of England’s Monetary Policy Committee, and Victoria Chick, emeritus professor of economics at University College London, savaged the record of the Conservative and coalition governments.
“We have had 10 years of near-zero
productivity growth,” they wrote.
“Corporate investment has stagnated. Average earnings are still lower than in 2008. A gulf has arisen between London and the South East and the rest of the country. And public services are under intolerable strain – which the economic costs of a hard Brexit would only make worse.”'

If you don't like Corbyn and Labour fair enough. But the economic argument for preferring the Conservatives over Labour is without any merit whatsoever. Voting Conservative in this election is like voting for Brexit: it's a values-based decision rather than an economically rational one. Which again is absolutely fair enough. Except that the values here are very explicitly racism, xenophobia, authoritarianism, mendacity.
