Liberals, schliberals. Money is money, wherever it comes from - and public projects can very well stimulate the economy, especially when the private sector is struggling. Unfortunately, this can lead to debt - but doing nothing can hit people even harder.
And considering how people on your political side were berating foolish spenders for causing the housing bubble, it’s funny that you’d talk about austerity only in the government sector. Yes, the government should not overspend - yet somehow that wasn’t a problem when your guys were in office.
