And the effective tax rate went down

Not really.

Effective tax rate didn't go down

Hw Bush rose taxes actually

I'm talking on the rich btw, not people in general

Clinton did the opposite

Yes thats the rich

top 1% and 0.1%

Clinton didn't do the opposite, they both raised taxes

Obama added to the debt aswell, which is another problem.

But Obama did not increase taxes

Obama cut the deficit in half

Clearly not, when effective taxes fell

But he didn't increase taxes

he extended the Bush tax cuts

which is where your argument immediately falls apart

As revenue rose aswell

He increased the top marginal tax rate

No he didn't

He kept the middle class tax cuts

Yes, he did

The top marginal rate was increased from 35% to 39%

No he didn't.

Hw Bush rose taxes and Clinton cut taxes

as the effective tax rate fell

so in effect you admit the tax cuts helped

and didn't cause a deficit

Reagan cut taxes and tax revenue boomed up, but he increased spending.

Thats why

It seems people who cut taxes love to increase spending, apart from Coolidge who cut taxes and cut the debt by a 1/3rd

I'll get back on this later

But why do boom and bust cycles happen? It's not tax cuts or deregulations, or any supply side policies

When central banks( such as the FED) expand credit well beyond their own assets and by the funds of their clients, often supported or encouraged by the setting of low interest rates by a central bank. This additional credit flow into the economy from increased borrowing for capital projects stimulates economic activity. Projects which would not have been started before, seem now profitable, creating malinvestment. They increase demand for production materials and for labor and their prices rise, which, in turn, leads to an increase in prices of consumption goods. If the banks would stop the extension of credit, the boom would be rapidly over. To prevent the sudden halt of this boom (and the resulting collapse of prices), the banks must create more and more credit, and the prices will rise even more.

But this expansion of credit cannot continue forever. There is no additional capital or labor; there is only more money (and debt). The means of production and labor which have been diverted to the new enterprises have to be taken away from others. Society is not sufficiently rich to permit the creation of new enterprises without taking away from others. As long as the expansion of credit is continued this will not be noticed, but it can't be pushed indefinitely. The inflation and the boom can last only as long as the public thinks that the prices will stop rising in the near future.

This is the true concept behind the business cycle

Mhm...

I don’t know how people can support socialism/communism honestly

It’s a fact it doesn’t work

And free market capitalism does
