Clearly, you have never run a business. If you admit that you have no idea what you are talking about, then you will find that things will be more open to your understanding.
"What sort of business goes into business without saving earnings for uncertain economic future?"
The majority of businesses are small businesses, and they employ the majority of people. Starting up a business is a very expensive proposition- many business plans show the first number of years in the "red". If the business is run right, and turns out it provides something desired, it can turn this around quickly. But then along comes the government, holding out its hand for "its" cut, plus all the expenses to deal with the onerous, and often useless, government regulations.
In spite of the imgflip liberals' insistence that "tax cuts for the rich" only benefit the rich, what you are saying is that the "rich" aren't saving enough (riches) in order to take care of their employees.
Businesses and true unemployment have not been better in decades than during Trump's tenure. History shows, repeatedly, that nothing is worse for the working class than having Democrats in control.
You are right to say that the last two+ years of liberal policies surrounding Covid have benefitted large business, though. For some reason, we could all go and cram ourselves into Walmart to 'share' Covid, but small businesses were hit hard with the lockdowns and mandates. Why would all of those Democrats mayors, governors, and president push for policies that harm the largest employment sector, small business, if they are the Party of the working class?
The answer is simple- they are not. And if they didn't have the MSM in their back pocket, more people would see this. Of course, it is still their fault they believe the propaganda, IN SPITE of what they are personally experiencing daily.
