Well...I can't speak from an "MBA's" perspective, because there isn't 1 MBA perspective.
In terms of the way the world works, I can say that politicians are not in the business of running the world the way it should be run - they are in the business of politicking.
It has become fanciful in the last decade or so, to blame bankers, wall street, the 1%, capitalism, etc. for all the worlds ills - but that's just not the case.
Politicians (many who I support also) are just as guilty.
Here is 1 truism that no politician of a heavily indebted country will say - bond markets are dead right.
If they demand a higher yield on a country's debt - it isn't because there are some "nefarious speculators" trying to make bank off of the demise of the poor people in that country. It's because the stupid policymakers and politician s have fleeced the country, the affairs are not in order and in order for them (bond market investors) to lend to your country in the crappy state it is in, they charge more than they will charge to lend to the US Treasury, Germany, etc.
Likewise, if the bond markets are showing very low yields to America despite all the rhetoric of America's economy in shambles and the debt-to-GDP ratio being too high at 90% - clearly something else is at work and the situation is not as bad as it seems. Financial markets are forward looking indicators - and by all indications, as a general rule, when it comes to properly (and easily) communicating what is TRULY happening with the state's finances, they tend to be spot on.
The issue is that politicians hate it because bond markets show up their lies and untruths. So they blame 'wreckless speculators' and tax bankers. When half of the time, the investors that are wrecking their bond yields are not even BANKERS!
But...it sounds good in a newsbyte because people like to believe conspiracy stories about the wealthy bankers that are enslaving the masses with interest on debt.
The fact is, debt, equity financing & capitalism in general have been the best mechanisms for growth, poverty reduction and standard of living increases over the past few centuries.
Most things you hear politicians blame things on, are just simply scapegoats that people accept because they know no better.
