Repeating a drawing between nodes

Question

Using the following code

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{verbatim}
\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{arrows, arrows.meta, backgrounds}
\begin{document}
\begin{frame}[t]
\frametitle{tree}
\pgfmathsetmacro{\inct}{1.96}
\pgfmathsetmacro{\inc}{1.2}
\pgfmathsetmacro{\incc}{.3}
\pgfmathsetmacro{\yc}{1.88}
\pgfmathsetmacro{\incyc}{1.1}
\tikzset{cano/.pic={
\draw [red, line width=\inc mm] (0,0) node (o){} circle (\incc) (135:\incc) -- (-45:\incc);
\begin{scope}[on background layer]
\draw [blue, line width=\inc*.8 mm, -latex] ([shift={(90:\incc*1.6)}]o.center) -- +(-90:\incc*4.4);
\draw [red, line width=\inc*.8 mm, -latex] ([shift={(0:\incc*12)}]o.center) -- +(180:\incc*8);
\end{scope}}}%circle arrow no
\vspace {-.8cm}
\begin{tikzpicture}[scale=.9, transform shape]
\node[black] at (0,0) (begin) {Education};
\node[black] at ([shift={(-90:\inct*1)}]begin.center) (nb) {Investment};
\node[black] at ([shift={(-90:\inct*2)}]begin.center) (nc) {New factory};
\node[black] at ([shift={(-90:\inct*3)}]begin.center) (nd) {Local employment};
\node[black] at ([shift={(-90:\inct*4)}]begin.center) (ne) {More tax revenue};
\node[black] at ([shift={(-90:\inct*5)}]begin.center) (nf) {Better public services};
\begin{scope}[yshift=-11.cm]
\foreach \position in {(0,\yc*\incyc*1), (0,\yc*\incyc*2), (0,\yc*\incyc*3), (0,\yc*\incyc*4), (0,\yc*\incyc*5)} \draw \position pic {cano};
\end{scope}
\end{tikzpicture}
\end{frame}
\end{document}

I would like to do the following:

1. repeating the circle/arrow drawing between the nodes, which does not look symmetric

2. make the text left aligned, not centered

to look like the following figure

Answer 1

I use my previous answer on your question:

\documentclass[tikz,margin=3mm]{standalone}
\usetikzlibrary{positioning,calc}
\def\yourcommand (#1); {
    \coordinate (center) at ($(x#1)+(1.7,-1)$);
    \begin{scope}[scale=0.4]
        \draw[line width=.75mm,blue,-latex] ($(center)+(0,1.5)$)--($(center)+(0,-2)$);
        \draw[line width=1.5mm,red] (center) circle (1 cm);
        \draw[line width=1.5mm,red] ($(center)+(135:1)$)--($(center)+(-45:1)$);
    \end{scope}
    \draw[line width=.5mm,red!70!black,latex-] ($(center)+(.75,0)$)--($(center)+(2.5,0)$);
}
\begin{document}
\begin{tikzpicture}[every node/.style={font=\sffamily}]
\foreach \i in {0,...,5} {\coordinate (x\i) at (0,-2*\i);}
\node[right=1cm of x0] (edu) {Education};
\node[right=1cm of x1] (inv) {Investment};
\node[right=1cm of x2] (fac) {New Factory};
\node[right=1cm of x3] (emp) {Local Employment};
\node[right=1cm of x4] (tax) {More Tax Revenue};
\node[right=1cm of x5] (pub) {Better Public Services};
\foreach \i in {0,...,4} {
    \yourcommand (\i);
}
\coordinate (centerleft) at ($(x2)+(-1.25,-1)$);
\draw[line width=.75mm,blue,-latex] ($(x5)+(0.75,0)$) to[out=180,in=-90] (centerleft) to[out=90,in=180] ($(x0)+(0.75,0)$);
\begin{scope}[scale=0.4]
    \draw[line width=1.5mm,red] (centerleft) circle (1 cm);
    \draw[line width=1.5mm,red] ($(centerleft)+(135:1)$)--($(centerleft)+(-45:1)$);
\end{scope}
\end{tikzpicture}
\end{document}

Edit 1:

To add text to the red horizontal arrow, we can add more arguments to the command:

\documentclass[tikz,margin=3mm]{standalone}
\usetikzlibrary{positioning,calc}
\def\yourcommand (#1) node[#2] #3; {
    \coordinate (center) at ($(x#1)+(1.7,-1)$);
    \begin{scope}[scale=0.4]
        \draw[line width=.75mm,blue,-latex] ($(center)+(0,1.5)$)--($(center)+(0,-2)$);
        \draw[line width=1.5mm,red] (center) circle (1 cm);
        \draw[line width=1.5mm,red] ($(center)+(135:1)$)--($(center)+(-45:1)$);
    \end{scope}
    \draw[line width=.5mm,red!70!black,latex-] ($(center)+(.75,0)$)--($(center)+(2.5,0)$) node[#2] {#3};
}
\begin{document}
\begin{tikzpicture}[every node/.style={font=\sffamily}]
\foreach \i in {0,...,5} {\coordinate (x\i) at (0,-2*\i);}
\node[right=1cm of x0] (edu) {Education};
\node[right=1cm of x1] (inv) {Investment};
\node[right=1cm of x2] (fac) {New Factory};
\node[right=1cm of x3] (emp) {Local Employment};
\node[right=1cm of x4] (tax) {More Tax Revenue};
\node[right=1cm of x5] (pub) {Better Public Services};
\yourcommand (0) node[right] {Some text};
\yourcommand (1) node[right=1cm] {Dummy text};
\yourcommand (2) node[midway,above] {Hello};
\yourcommand (3) node[below] {Some stuff};
\yourcommand (4) node[above] {Some other stuff};
\coordinate (centerleft) at ($(x2)+(-1.25,-1)$);
\draw[line width=.75mm,blue,-latex] ($(x5)+(0.75,0)$) to[out=180,in=-90] (centerleft) to[out=90,in=180] ($(x0)+(0.75,0)$);
\begin{scope}[scale=0.4]
    \draw[line width=1.5mm,red] (centerleft) circle (1 cm);
    \draw[line width=1.5mm,red] ($(centerleft)+(135:1)$)--($(centerleft)+(-45:1)$);
\end{scope}
\end{tikzpicture}
\end{document}

Answer 2

an alternative, with using tikz library arrows.meta (for arrows), matrix (for positioning of nodes) and calc (for drawing of symbols). symbols with arrow are defined as node style using path picture:

edit: adopted to beamer document class. image size is now determined by selection radius of symbol. appropriate values seems to be between 0.15 in 0.35. scaling with scale=... doesn't work.

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, calc, matrix}

\newcommand\ppbb{path picture bounding box}
\begin{document}
\begin{frame}[fragile]
    \begin{tikzpicture}[font=\footnotesize\sffamily,
 short/.style = {shorten <=1mm},
  symb/.style = {minimum size=4*\r cm, 
                 path picture={
                 \draw[line width=3*\r mm,blue,-{Triangle[angle=90:1pt 2]},short]
                        (\ppbb.north) -- (\ppbb.south);
                 \draw[line width=4*\r mm,red] (\ppbb.center) circle[radius=\r]
                            ($(\ppbb.center)+(135:\r)$)--($(\ppbb.center)+(315:\r)$);
                                },
                node contents={},
                pin=0:{#1}},
symb/.default = {},
every pin/.style = {pin distance=13mm,
                    pin edge={line width=2*\r mm,{Triangle[angle=90:1pt 2]}-,red}
                          },
                        ]
\def\r{.25} %by size of symbol you can scale image size
