Here we go again. President Trump is promising another tax cut.

Don’t get me wrong, I love it when my taxes decline, even if by a few bucks a paycheck. But is this really the time for politicians to be giving things away, whether it’s free tuition or cost-nothing medical care or another tax cut?

The US debt level is now above $23 trillion. And it is growing at about $1 trillion a year.

By cutting taxes, the US Treasury will get less of our money (hooray!) but it will also have less to spend on things the government buys (like roads, armies and those jets that the president and Congress get around in).

And — I know this is getting cliché — all of that debt will have to be borne by our children and grandchildren.

People who lived during World War II are known as the Greatest Generation. If we keep behaving like we have been, our generation(s) will be known as the Selfish Generation.

It’s pretty clear why Trump is going to propose cutting taxes again after doing it in 2017.

There’s an election coming up. And Trump’s Democratic challengers are offering all kinds of incentives — aka bribes — to get people’s votes.

Those promises are irresponsible with the US debt being as high as it is and going higher by more than 5 percent each year.

Most people are like me. They want more money in their pocket and they want it now.

But on sober reflection — especially when looking into their kids’ eyes — they will realize that what we are doing is wrong.

And is screwing future generations what America is really about?
