You line of thinking as one issue. It relies on the assumption you will always be on the right side of the economic downturn. You won't.
If the economy because too structurally broken then conventional methods to stimulate it will not work in times of recession. Then that leads to a situation where the economy will be in a depressed state for an extended period of time, which will eventually drag down the value of your capital assets, and keep them depressed. Can't buy low and sell high if the price stays low. Can't buy low if your wealth is eroded by said downturn. Your ways of thinking only works because the federal government protects capital so much. But if the government is runs out of options, then you are left to fend for yourself. What's a rental property good for if there is a lack of available tenants, climate change causes insurance rates to sky rocket, and powerful incumbent landlords get more market power. What happens when the government is humstrung to pull the economy out of depression.
You are all for pumping more uncertainty a risk into the system just cause you think you will always come out on top. But if things continue the way they do, it increases the chances of you being on the wrong side of a downturn, and never being able to benefit from an upswing.
On the politicial side, if we enter a mass depression (which Obama saved us from), then people will vote in Bernie Sanders types in mass. And then you face the prospect of mass nationalization of private assets. So they if you guys don't want full blown socialism, they you should warm up to a balanced well manged mixed economy.
I'm the one trying to protect people like you because I want to structurally strengthen the economy to get rid of the uncertainty and downside risk. I'm a liberal progressive dentist telling you that you either let me fill that cavity now, or else socialist dentist gonna root canal it later, or even the communist dentist gonna want to pull the tooth and put in a publicly own implant.
Smarten up now, or keep enjoying that right wing sugar and thinking the pain will never come. Your choice, b.
