I'm not so sure about some of this. What's wrong with 4% inflation? [/quote]
It's higher than 2%. It hurts the middle-class and in particular it hurts savings, so it increases the cost to the state of the welfare state, particularly (in the long term) as regards pensions. But more importantly, as I said before, the higher the inflation, the faster it tends to rise, so the harder you have to work to hold it down.
Think of it as path along a the side of a cliff. There's nothing inherently fatal about walking right at the edge of the path, right at the cliff-edge. But it gives you little leeway if things go wrong. You try to walk nearer the middle of the path, because it lets you be freer to deviate to either side.
It is, similarly, better to run at 2% inflation, so that an inflationary hit takes you to 5%, than to run at 4%, where an inflationary hit can take you to 12%. Because the higher it goes, the harder you have to work to keep it down, or else it gets out of control. [the last time we crashed out of a european system, in the ERM crisis, interest rates got up to 15%...]
The recent recession hasn't really been relevant in that regard, because the problem was the opposite: central bankers were desparately trying to increase inflation. They did, and overshot, which is partly why the recovery was so slow, and only sped up once inflation had been brought under control a bit more. [Inflation encourages people to have less money in the bank, which makes it harder for banks to lend money while keeping to sensible ratios]. But in truth, at least in the UK inflation has never gotten back under control since - an inflationary boom was followed by a near-deflationary bust, and now it's rising sharply again.It would be hard to prove claims one way or another, since where inflation really causes things to happen is in central bankers' heads; they are eternally terrified of the 1970s and therefore keep economies severely throttled at all times. The post-2008 experience hasn't been a great advertisement for near-2% inflation.
I said that LOW inflation relatively hurts the rich. High inflation moves wealth from the middle class to the rich, whereas low inflation doesn't, so it's relatively harmful. [before you object: sure, recent economic policies have moved wealth from the middle class to the rich, but that's not because of low inflation, but because of low taxes and low spending and low regulation]. Low inflation favours savings over investments, and the rich have proportionally more investments.And why would inflation hurt the rich?
I realise that conspiracy theories are the fashion these days, but they're not always true. Governments care about the rich, but they also care about things like banks, and about votes. And in any case, in most western countries monetary policy is not longer controlled by the government.Your argument seems to be that it's the middle class that are harmed by it... but that doesn't say anything about the rich one way or another. It's certainly suggestive that central bank policy is almost always pro-austerity and anti-inflation. It's a little strange to suggest that that policy is not what the rich want. (The rich may be foolish to want it, but that's another story.)
Low inflation is targeted not because there's a cabal of plutocrats paying people off, but because economists agree that that's the best thing for the stability of the economy. And ultimately because the middle classes get really, really pissed off if you let inflation rise too high for too long.
Yes, inflation reduces the value of existing fixed-rate debts. But it causes higher interest rates, which means that new and variable debts cost more. Your mortgage might cost you less in real terms, but your credit card loans cost you more. Obviously the exact effects vary with the country: in the US, 90% of people have fixed-rate mortgages... but in the UK, only 50% of people do. What's more, 'fixed' rates aren't fixed - on average they're only fixed for two to five years at a time, so an inflationary episode lasting longer than that will hit even the fixed rates.Also, did you get the bank debt part backwards? Inflation lessens debt, at least if it's fixed-rate. And here, at least, the minimum wage doesn't keep up with inflation, so that definitely hits the poor.
In the broader picture, new fixed rate loans incorporate not only current inflation, but the risk of future inflation, which gets higher as current inflation gets higher. So any increase in inflation has a disproportionally large effect on debt interest for fixed term loans (even before factoring central bank policy raising rates further). And that tends to push more people toward variable rate loans where possible.
So yes, if you specifically are someone who has a really big loan fixed at a completely invariable rate for ever, and don't intend to take on any more loans in future, then inflation is good for your debt. But overall, higher inflation will tend to increase the real debt levels of the middle classes.
Regarding the minimum wage, the effects are complicated. Yes, nominal price rigidity will lower the wages of the poorest... but in the process it'll also help reduce unemployment. The wage/unemployment payoff is complicated and depends a lot on specific factors of the local economy. [which is why demanding the same minimum wage in both new york and montana is not economically that sensible]
