The Tories have taken the national debt from £700bn (after the crash) to £1500bn.
And under the Blair Government,
Labour eradicated the budget deficit and remains the only Government to have ever do so in the past quarter of a century. The Brown Government ran a deficit at 1% of GDP, compared with the Tories who are running it between 2-6% of GDP and dropping. This idea of "Labour = bad for economy" is peddled by simpletons who can't read line graphs.
And finally, for the very last time, an economy isn't a shopping bill with a spend/gain. You spend money specifically to INCREASE future tax income, public spending is investment.
Austerity is an economic failure
It's funny that when you ask Tories if we should invest in other countries, they say Yes because it will stimulate their economy and give us a strong trading partner in the future but if you ask them if we should invest in our country they say no and we should save money instead. Could it be because their cuts are ideological rather than economical?
Think of it this way. Things need to be paid for. Either public debt grows or private debt like credit cards and loans grows. You pick one.
