As someone who has actually taken whole assed courses on economics.... What economics?
Whether conservative or liberal, politicians don't make economic decisions, they make political decisions.
I have yet to see any politician who consistently made, or even publicly recognised, the better economic decision.
Economically, a well trained, and healthy population is a good thing. So providing relief for the costs of being healthy through something like a healthcare program, is in everyone's best interest. Ensuring that people can get the training they need to be the most efficient they can be, is in everyone's best interest. These things are good for the economy.
Conservatives make it seem like they're making choices that are good for the economy, and they certainly make statements that try to convince everyone that's the case, but bluntly, they make capitalistic decisions. Decisions that help capitalists. If they can rob, steal, kill, or maim someone to bump profits, they'll do it, and their friends in government will help them do it, and get protection for doing it.
They're not interested in the economy, they're interested in their pocketbook, and whatever make it fatter. Even if the cost is future economic downturn, they'll do it if it bumps profits this quarter.
.... Like firing an entire department to save on the wages of the people that they fired, when those people are still needed, and now you'll need to spend more money to hire replacements for almost all of them, but this quarters numbers will look amazing, and the CEO, and his buddies in the c-suite will get their bonuses, and the shareholders will get a few dollars more per share in dividends this quarter.
They wouldn't know good economics if they were surrounded by it. They can't see that far.
