On at least one point I'm afraid you're way off target. While wealthier people may be able to afford having more kids, they actually have fewer than those who are less well-off.
The data (https://www.statista.com/statistics/241530/birth-rate-by-family-income-in-the-us/) prove there's an almost-linear negative correlation between income and fertility.
Regarding your assertion that "poor people must never look anything but poor," which I've read in some of your other articles too, that's wrong too IMO, or at the very least painting with a way-too-broad brush.
If you're poor but want to spend your money on new, well-fitting, attractive clothes, go for it. I certainly don't care. Similarly, if you choose to buy a fancy new car every 2-3 years, or replace your laptop and/or phone with the latest and greatest each year.
However, if you spend so much of your money on such non-essentials that you can't afford to heat your home and/or buy food and medicine you need, are you prepared to pay the cost, or would you expect someone else (say, the taxpayer) to bail you out?
If you expect someone else to bail you out, then yes, I'd mind, especially if that someone else is me (e.g., if it means you're saved by the government from the consequences of such choices).
You see, it isn't at all that as a poor person you "must" look poor. It's that if you can't truly afford things that look better, why would you expect others to pay for those nicer things for you?
I'm very much in favor of having a far more robust welfare system than we have in this country to make sure people have the things they need (e..g, nutritious food, medical care, shelter, etc.). And I'm willing to pay higher taxes to that end.
However, I'm not willing to pay higher taxes to provide anyone with luxuries that they can't afford. And the things I listed above - new laptops and phones each year, new cars every 2-3 years, new brand-name designer clothes - those are the kinds of luxuries each person should pay for by themselves if they want them.
And that also means they can't expect public assistance even for needs if they spend their money on such luxuries.
