I don't live in the US so sadly I can only speak for where I live, the UK
Economic conditions worsen, crime goes up. Very simple. There are a multitude of reasons for this, if you need food or shelter - you need food or shelter, full stop. We'll put that one aside, as its dealt with later.
However often its down to addictions, and I don't just mean the obvious ones, which exist. I mean addictions to needing to have as much as the person next to you, or the next console the day it comes out. To buy a bigger house than your father did, have 10 bikes sitting around your home, things that don't really mean that much, only to the person getting them.
Which is fine people like things that make them happy, who doesn't, but things you are not in control of, the urges to need something rather than want something, those addictions completely sap you of income, and often do lead to crime because when the downturn happens people are maxed to their limit spending wise. There is no sense of needing to keep a chunk of income in reserve, or on the other end of the scale, food in reserve.
I get it I do about the food, been there when it was hard to find, live long enough and you might have that issue too. This is instead handled by the community and country as a whole having enough put away in times of crisis. Say what you want about Germany, when all this hit, they were so much better prepared than the UK, I have a lot of respect for them
. I know everyone is suffering now but those kinds of things make a difference, the country is the individual mindset, it is the collective will of those who are able to be engaged by it. I haven't been engaged for years politically. Its the hype word to say at the minute but banking bonuses make me doubt the sanity of anyone at the top in the UK. That is personal greed gone mad, especially since there is so much public dissatisfaction with them, and highlights what i indicate in the open paragraphs. Most of the political class in the UK is, rightly or wrongly imprinted in my mind to be of this mindset.
There is the other issue political class, it should be working men and women, businessmen, scientists, farmers, soldiers, janitors, policemen, accountants, and yes negotiators or diplomats there too, not a singular political elite divided along party lines ruling the country, what are party lines to me? I'd rather be electing individuals with experience, but that is the UK for you still for the most part, a political elite and some odd notion that parties make a difference aside from campaigning together for mutual benefit. Another reason why an individual candidate when they stand, gets a lot of interest here, is because he or she is standing as themselves, and you can judge them as themselves whether you want them leading you and your children without the murky affiliations which have less meaning.
Finally there is the issue of interest, and this will be more of a sticking point, as I like free money too. Interest on money is what drives much of inflation, especially when set 'above' inflation. Someone with a more of a head for numbers will probably look at that and add more to it, but interest is a problem, it brings us full circle around into what I listed above.
Again I am sure the US is different, so don't take this as for the US, this is for the UK.
