Oh, and this "everyone lies all the time so we can't know what is true" is a very Russian narrative called The Firehose of Falshoods.
This article is a good explanation of why this epidemic of grifters has taken over conservatism in the US.

Deception is central to the contemporary right for two reasons. One is that they’ve discovered, over a long period, that it is highly profitable to mobilize people’s fears and resentments around mythical issues. You can pull in vast sums of money from the right-wing base. The second reason is that facts don’t work for them. It is very hard, at this point, to make arguments on behalf of their positions that are fact-based. They push lies, conspiracy theories, fantastical inventions that support their ideological positions. To take one example, there is an idea that the minimum wage costs jobs. Not true. It’s been debunked. No respectable economist believes it. Or if you cut taxes, you’ll generate economic growth. Not true. It’s been disproven over again. So, they rely on falsehoods. Now, it is the “global elite” that is responsible for our problems—the faceless people at Davos. There is a large cohort of Americans who you can deceive with these myths.
""" Steve Kaplan of Chicago Booth strongly agreed that raising the wage would adversely affect the unemployment rate: “A $15 minimum wage rise makes entry level/low wage jobs very expensive. It would move the US to be more like France, Italy, etc.”
David Autor of MIT disagreed: “I don’t think the evidence supports the bold prediction that employment will be substantially lower. Not impossible, but no strong evidence.”
And Oliver Hart of Harvard was uncertain: “I worry that it will, but we don’t know enough. Firms may raise prices and the Fed may accommodate some inflation. But the change is large.” """ [1]
And from NPR on tax cuts: """ Many — but by no means all— economists believe there's a relationship between cuts and growth. In a 2012 survey of top economists, the University of Chicago's Booth School of Business found that 35 percent thought cutting taxes would boost economic growth. A roughly equal share, 35 percent, were uncertain. Only 8 percent disagreed or strongly disagreed. """ [2]
It doesn't seem like these things are as proven as you think they are. I encourage you to step out of your echo chamber and challenge your ideas more, and try to be less partisan in your analysis.
