That's not how legislators act at all
You think legislators, given an option will actually make painful cuts instead of just spending more and taxing more? Really? A look at history would suggest otherwise.
, and as I mentioned (and asked you to go look at again), deficit spending in our current situation does not cause inflation. (in case you haven't noticed, inflation has been quite low the last few years despite massive deficits) Inflation will only return when the economy has stabilized.
It doesn't cause immediate inflation, but it sets the gears in motion for future inflation. Also, inflation has been artificially "low" for the past few years. Housing costs have declined greatly, but commodities and food have gone up in price -- by a lot. Inflation is taking place, it's just getting masked right now and unless we get the fiscal house in order, it's going to get a lot higher.
Additionally, there is no evidence whatsoever that legislators base their current spending priorities on the risk of inflation 10 or 20 years down the line. Like, absolutely zero. To think that some nebulous future risk inhibits current spending action is a fantasy.
Then what does? Why hasn't congress simply spent an additional 5 trillion or so to really boost the economy? There MUST be at least some connection between revenues and spending, whether it's political pressure, future inflation, borrowing costs doesn't matter. The connection might not be incredibly strong (or we wouldn't be in the hole as far as we are), but it exists nonetheless or the spending would be astronomically higher.
The current political environment has the public justifiably concerned about our financial situation as a country, so politicians are starting to feel the heat and don't want to be seen as raising the deficit. Increasing revenue just gives them an out to spend more and yet claim to not be increasing the deficit.
So, like I said. Spending not constrained by revenues
Controlled, no. Constrained, yes, at least to degree.
but tax increases for the future still needed for when the economy gets better.
No doubt tax increases will be needed to pay for everything.
