This statement is very far from the truth.
The current acting government actually cut investment spending to record levels as part of their renewed austerity effort, both with higher taxes and slending cuts, that resulted in record low deficit spending.
While the previous goveremt of Portugal focused on higher income taxes focused on the middle/upper class and public sector workers, the current acting government forced increases in gas prices mixed with off-the-bool spending cuts in the form of captivation of expenditures.
The key factor in Portugal's economic turnaround is the fact that the austerity program was actually surprisingly effective at fixing Portugal's problem, as is demonstrated by the fact that the portuguese recession that started way back in 2008 ended in 2014, right before the end of the austerity program.
