Trump is a Democrat at heart, and a selfish bastard to boot. What he's railing against above is the elimination of passive real-estate investing in 1986 in return for lower tax rates. I know about this because I invested in some nursing homes as a passive investor, took two years of depreciation, then lost my ass when this deduction was eliminated. Yes, my taxes overall were lower, but it took years to recover the investment.
The tax reform Reagan championed in 1986 saved Social Security for 20 years, but it was the right thing to do. Being able to deduct a $100K investment over five years (that's a $20K deduction per year) was attractive, which was why so many small investors jumped on this. Eliminating it was painful, but the best thing for the economy overall. It juiced the stock market, removing passive real estate from investment portfolios.
Naturally, Trump hated this and, interestingly, his ability to borrow got tougher and his bankruptcies began in 1989, three years after this tax reform.
Now he wants to cut taxes on the middle class but raise it on high income people, cut military spending and yet grow the military, and do nothing to strengthen entitlements by reforming them.
I was accused earlier by a Trumploo of being economically stupid. Maybe I am, but even I recognize you can't do what Trump wants to do and eliminate the national debt at the same time.
